99 f350 super duty, wipers would only come on sometimes. I changed wiper motor now they still don't work


The generic electronic module (GEM) responds to the windshield wiper control commands by interpreting inputs from the steering column multi-function switch. The speed dependent wipers will compensate for the extra moisture that accumulates on the windshield at higher speeds, except when the multi-function switch is in the INT 1 position. At higher speeds, the speed dependent feature shortens the delay between wipes when using the variable interval wipers. Delays will automatically adjust at speeds between 16 and 105 km/h (10 and 65 mph).
Testing should be done before replacing any parts . And if you don't know about (GEM) Control module controlled system's your best bet , take it to a qualified repair shop . The first place to start trouble shooting these systems is with a scan tool that can read GEM module codes .

06 kia sportage 2.7 will not turn over. ..starter tested good, new neutral safety switch, please help


You need to test the electrical circuit , starter relay in the engine compartment . Is there B+ voltage at the smaller gage wire on the starter solenoid when cranking ( or trying to crank the engine ) ? Videos on you tube , testing from relay base ( where the relay plugs into ) Find the start relay in the fuse / relay box an pull it out . Look on the bottom of the relay , you should see four sets of numbers ! 30 , 87 an 85 , 86 . > 30 an 87 are the power side of the relay . 30 should have B+ voltage ,if not ignition #2 30amp fuse is blown . If there is B+ voltage you can take a jumper wirer ,an jump 30 to 87 > 87 goes to the starter solenoid . Jumping 30 to 87 will engage the starter .Checking for B+ voltage at pin 85 while trying to crank the engine, if there is b+ voltage you know the ignition switch is good an so is the transaxle range switch (neutral safety switch ) ! Does yours have a burglar alarm ? If so then there is an other part burglar alarm relay ! By testing at the relay you can tell which part of the circuit is bad ! Plus testing the heavier battery positive cable also needs to be done . Voltage drop testing the cables Starter Voltage Drop VEHICLE RELAYS Operation Diagnosis VEHICLE RELAYS Testing from the relay base This would cost you $86.00 to have this diagnosed at most auto repair shops. 1 hr .

How do I fix the horn on 2006 Impala


System Description
The horn PCB relay is non replaceable ,soldered to the underhood fuse / relay box. . You would have to take the box a part to get at it . Is the air bag light lit on the instrument cluster ? Could have an open wire in the Clock spring , do you know what a clock spring is ? It is inside the upper part of the steering column , It allows the steering wheel to be turned full right to full left keeping the horn an all the buttons an air bag connected electrically. When the horn button is pressed, ground is applied through the horn switch contacts and the horn relay control circuit to the coil side of the relay. The horn relay coil is then energized, causing the relay switch contacts to close applying voltage through the horn control circuit to the horns. For theft deterrent functions, the body control module (BCM) also controls the horn relay by applying ground to the relay control circuit to the relay.
Circuit/System Testing
With a test lamp connected to ground, probe each of the test points on the HORN fuse while activating the horns. The test lamp should illuminate at one or both of the fuse test points.
?‡'
If the test lamp does not illuminate at either test point, refer to the Horn Switch Test.


?‡'
If the test lamp illuminates, refer to the Horn Test.


Ignition OFF, disconnect the inline harness connector C275. Ignition ON, test for B+ between the horn relay control circuit terminal B and ground.
?‡'
If less than B+, test the control circuit for an open/high resistance. If the circuit tests normal, replace the underhood fuse block.

Momentarily connect a 3-A fused jumper wire between the control circuit terminal B and ground. The horns should work.
?‡'
If the horns do not work, replace the underhood fuse block.

If all circuits test normal, test or replace the horn switch

The PCB relay horn system consists of the following components:
?€¢
Horn switch

?€¢
Horn PCB relay

?€¢
Horn assembly

?€¢
Body control module (BCM)

?€¢
HORN fuse 15 A

My trunk will not open. When I take off battery cable and replace, it opens once. Is there an easy fix? relay etc?


When the rear compartment lid release switch is pushed, the rear compartment lid release signal circuit to the body control module (BCM) is grounded. BCM then grounds the coil side of the trunk release relay through the trunk release relay control circuit. With this voltage is applied to the rear compartment lid release actuator, opening the rear compartment.
Rear Compartment Lid Release Relay
  1. Ignition OFF, disconnect the trunk relay.
  2. Test for 65-90 ohms of resistance between terminals 85 and 86.
  3. ?‡'
    If the resistance is not within the specified range, replace the trunk relay.

  4. Test for infinite resistance between the following terminals:
  5. ?€¢
    30 and 86


    ?€¢
    30 and 87


    ?€¢
    30 and 85


    ?€¢
    85 and 87


    ?‡'
    If less than infinite resistance, replace the relay.

  6. Install a 10-amp fused jumper wire between relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Measure for less than 2 ohms of resistance between terminals 30 and 87.
?‡'
If greater than 2 ohms, replace the relay.


Rear Compartment Lid Release Relay Malfunction

  1. Ignition OFF, disconnect the trunk relay.
  2. Verify that a test lamp illuminates between the coil side B+ circuit of the trunk relay and ground.
  3. ?‡'
    If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ circuit fuse is open, test the voltage control circuit for a short to ground. If the circuit tests normal, test or replace the trunk relay.

  4. Verify that a test lamp illuminates between the switch side B+ circuit of the trunk relay and ground.
  5. ?‡'
    If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

  6. Disconnect the harness connector at the rear compartment lid latch.
  7. Ignition OFF, test for less than 5 ohm of resistance between the rear compartment lid latch ground circuit and ground.
  8. ?‡'
    If greater than the specifed range, test the ground circuit for an open/high resistance.

  9. Connect a test lamp between the trunk release relay control circuit and the coil side B+ circuit of the trunk relay.
  10. Command the trunk release solenoid ON and OFF with a scan tool.
  11. ?‡'
    If the test lamp remains ON all the time, test the control circuit for a short to ground. If the circuit tests normal, replace the BCM.


    ?‡'
    If the test lamp remains OFF all the time, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.

  12. Connect the harness connector at the rear compartment lid latch.
  13. Connect a 3-amp fused jumper wire between the switch side B+ circuit of the trunk relay and the voltage control circuit of the lid latch. Verify that the lid latch activates.
  14. ?‡'
    If the lid latch does not activate, test the control circuit for an open/high resistance. If the circuit tests normal, test or replace the rear compartment lid latch.

  15. If all circuits test normal, test or replace the trunk relay.
Component Testing
Rear Compartment Lid Release Switch
  1. Ignition OFF, disconnect the harness connector at the rear compartment lid release switch.
  2. Test for infinite resistance between the trunk release switch supply voltage and ground terminals with the switch in the open position.
  3. ?‡'
    If less than infinite resistance, replace the rear compartment lid release switch.

  4. Test for less than 2 ohms of resistance between the trunk release switch supply voltage and ground terminals with the switch in the closed position.
  5. ?‡'
    If greater than 2 ohms, replace the rear compartment lid release switch.

  6. Test for infinite resistance between each terminal and the lid release switch housing/case.
?‡'
If less than infinite resistance, replace the rear compartment lid release switch.


Could be the relay , could be the switch , could be a problem with the BCM !

The yellow wire that goes to the starter of a 96 chrysler sebring coupe does not have any power.


Hi, the most likely cause is the range switch on the transmission, but it could also be the relay or the ignition switch. You can diagnose by interrogating the socket under the starter relay using a 12 volt test light. The starter relay is probably in the box under the hood by the air filter box. Just pull the relay out, connect your test light clip to ground, and probe the socket while someone holds the key to start. If the ignition switch is good, there will be 2 hot terminals in the relay socket. Next, move the test light clip to battery positive and probe the socket again. Assuming the transmission is in park, there should be one terminal that lights the test light brightly and one that lights it dimly. If there is no bright light, the range switch is bad. If there is no dim light, the wire from the relay to the starter is bad. Finally, if all of the tests are good, the relay is bad. Please let me know the results of your tests for repair advice.

Driver side switch sticks/broken. Driver window


1. Seek a replacement switch via a local salvage yard.
2. Look in a Haynes manual ($20) for direct directions as to how to remove and replace it.

If the switch is simply sticking you can clean it using CRC QD Electronic Cleaner. Use the straw to shoot the cleaner in the gaps between the switch and face plate and then work the switch. (TEST A SMALL AMOUNT FIRST with a rag - this stuff can on occasion melt some plastics) better to know before you completely melt the button.

I have a 1999 explorer sport that the rear wiper does not work. I have already replaced the wiper assembly,checked the fuse under the hood, switched the wiper relay with another known to be good and tested...


Before replacing GEM modules test the electrical circuits ,don't guess . And if you don't know how to test your best bet take it to a qualified repair shop . These modules are capable of setting DTC'S diagnostic trouble codes , need an advanced type scan tool . Not a code reader . How did your test the switch ? Low voltage input to the gem . Plus there are two relays for the rear wipers . Did you pull the relays an test (with a voltmeter ) for B+ voltage on the control side and load side of the relay ? Is the GEM energizing the relay .
You people crack me up ,you have no clue .

switched the wiper relay with another known to be good and tested the wiper switch all are good,
Electric Testing Techniques You Need to Know

looking at wiring diagrams to see what all is involved in making the wipers work ,testing electrical circuits ,this is how you find electrical problems , not swap relays an just replace parts .
Here is a web site for free wiring diagrams. http://www.bbbind.com/free_tsb.html Enter the vehicle info. year make , model and engine size . Under system click body & accessories . Under subsystem click Wiper/Washer . Click the search button ,then the second blue link. Thats for the rear wipers . Do you know how a relay works ? Watch this video

VEHICLE RELAYS Operation Diagnosis . Do not assume the gem module is bad with out checking codes an testing the electrical circuit.
