Question about 2003 Jeep Grand Cherokee

1 Answer

Cruise control not working.

My cruise control will not light up or do anything.
I looked for loose wires or plugs and found a white 3 wire connector
under the instrument cluster that is not connected to anything.
I can't seem to find a spot to put it.
Is this my problem or is it a unused portion of the wiring harness?

    Yes, I check the fuses inside and under the hood early in the looking process.

    Any other thoughts?

    Thanks,

Most likely just unused wire, did you check the fuses, check them inside and under hood.

    do you have a multimeter check for power at the cruise actuator if it has power then the motor is bad and replacing it will make everything work

Intermittent Cruise Control Issue - cuts out when small bump in road is hit and may or may not re-engage after that.


Check the wire connector that plugs into the cruise control under the hood. Sounds like a loose connection. Remove the and reinsert the wire connector several times to make a better connection. Stepping on the brake pedal disengages the cruise control by a switch on the brake pedal, not the computer.

Cruise control won't switch on - light on dash switch not on - could it be a fuse? and how do I find it?


look in engine bay for cruis control actuator it will have a wired cable connecting to the accelerator throttle in the engine bay follow it back to find unit. Check for any electrical plugs that may be loose. Check also the brake Switch above the brake pedal as the cruise control should have a tap on to the wires if this switch. if the wires come loose the cruise control may shut down. Also follow the wires on the actuator see if any fuses connected to them.

Check the cruise control fuse. Do a visual check of all wiring relating to the cruise control system. Look for melted insulation, broken wires, burned wires and twisted wires without a wire connector. Repair any wire damage with the splicing and wire connecting tool and the right size wire connector for the wire you are repairing.

I have a 97 discovery.i found lately the cruise control is not working and the rear electric windows not working either. I checked all the fuses all ok and i checked the the switches for the rear windows...


Me a sparky too - found this on another website and it worked - for rear windows - you need to find a switched hot and splice it into the white wire going into the electric window ECM located on the far right side under the glovebox (I removed the glovebox, 4 7mm bolt on bottom to make easier). the white wire is staring right at you when you pull the glovebox out on the right side - part of a wire connector with purple.black.grey wires going into it. 12 gauge.

2003 Honda accd Cruise control power won't stay on


With the car turned off and the battery disconnected, root around under the dash and find the wiring harness that comes down from the steering column. You may have to remove a dash panel or two to get at it. It should be connected to the car's main wiring harness with a plug of some sort. Disconnect the plug.

Using a multi-meter set to test continuity, test pairs of pins in the connector from the steering column, pressing the CC switch with each pair, until you find the pair that come from the CC switch.

Isolate the wires for these two pins behind the plug and scrape away a tiny bit of insulation with a knife blade, being careful not to cut through the wire. Test the wire pair again to be sure you've got the CC switch wires.

Cut the wires, leaving several inches of wire above the plug to work with. Using a good quality crimp connector (or soldering, if you know how and have the equipment), connect the two wires you just cut loose (the two coming from the plug, not the steering column).

Make sure there are no bare wires *anywhere* when you're done. Cover everything with heat shrink tubing or electrical tape, then use a tie-wrap to bind all the wires together again. Return the wiring harness to where you found it and re-install any dash panels you had to remove.

Reconnect the battery and go for a drive. The CC switch will be totally out of the circuit, but your CC should be permanently turned on.

Now here's the fun part. You'll have an extra momentary-contact switch on your steering wheel that's not doing anything. Just think of the possibilities... You could use it for an auxiliary air horn like on a semi-truck, or you could wire it into your brake lights so you could screw with tail-gaters without actually stepping on the brakes. Look for the switch somewhere on your brake pedal assembly and add two wires from the old CC switch to the contacts on the brake pedal switch.

Cruise control just quit working


Check fuses/relays and make sure they are all good; if so check the electrical wiring/connectors in the dash. Jeeps are notorious for loose wires in the dash.

Cruise control indicater lights are on but will not engage


Check the cruise control module connector, see if it looks good and there is power to the module over one of the white wires in the 10 pin connector.
There are two white wires going to the module which is located at pins "G" and "J". There should be no voltage at pin "G" until the brake switch is applied. This switch is also used to operate the brake lights. The two wire colors on this switch are white and orange. At pin "J", this signal goes to the PCM to tell it that the cruise control module is engaged. Here is the info on the cruise control connector:

Pin A: gray - cruise control on switch signal: 12VDC with cruise switch on
Pin B: dark blue - cruise control set/coast switch signal: 12VDC with switch pressed
Pin C: gray/black - cruise control resume/accel switch signal: 12VDC with switch pressed
Pin D: brown - cruise control release signal: 12VDC with brake pedal not pressed: 0V when pressed
Pin E: black/white - ground
Pin F: brown - ignition 3 voltage: 12VDC with ignition on
Pin G: white - stop lamp switch signal: 0V with brake pedal not pressed: 12VDC when pressed
Pin H: dark green - cruise control inhibit signal: 0V if PCM detects an inhibit condition
Pin J: white - cruise control engaged signal: voltage (unsure of value, either 12VDC or 5VDC) when signal engaged
Pin K: dark green - vehicle speed signal: 1 to 5 volts depending on speed

This view of connector is facing it after it is separated.

Trying to post the connector view, the lines may not quite line up, but at least it should show you the pin positions.

1989 plymouth horizon check engine light on


Code 34 is set when the computer does not detect a voltage to and through the speed control servo. The cruise control computer is built into the PCM, which grounds two windings in the servo mechanism to regulate the vacuum applied to the servo diaphragm.
Note: All Chrysler corporation fuel-injected engines have the computer circuitry and software for the cruise control system installed, even if there is no cruise control installed on the vehicle. If there is no cruise control installed on the care or truck, the computer will interpret this as an open winding and set code 34.
First: turn the key ON, turn the cruise switch ON, and look for +12 Volts on the dark blue/red wire that connects to the servo mechanism. This circuit is fed:
  • from the ignition switch through to 10 (dark blue wire)
  • from fuse 10 to the steering column (white/red wire)
  • through the clock spring to the cruise control ON/OFF switch on the steering wheel (white/red wire)
  • back through the clockspring to joint connect "C" (yellow/red wire)
  • to the brake lamp switch under the dashboard (yellow/red wire)
  • through the firewall from the brake switch (dark blue/red wire)
  • to the servo (dark blue/red wire) A break anywhere in this path (broken wire, bad brake switch, loose connector, etc.) will interrupt the 12 volt supply to the servo and set a fault code. Work backwards until you locate the break.
Turn the key OFF. Unplug the the connector from the servo and measure the servo coil resistances.
  • measure the resistance between the servo pin that connects to the tan/red wire and the servo pin that connects to the dark blue/red wire.
  • measure the resistance between the servo pin that connects to the light green/red wire and the servo pin that connects to the dark blue/red wire. The resistance in both cases should be above 0 ohms and less than infinity.
Disconnect the battery(s). Unplug the 60 pin connector from the PCM and check for continuity between the pcm connector and the servo connector for the tan/red wire (cavity 33) and the light green/red wire (cavity 53).
If no wiring problems are found, check the PCM connectors for corrosion, and reconnect. Reconnect the battery and test the circuit again. If the problem still exists, the PCM is probably bad. NOTE: Personally, if the truck was out of warranty I would try to find for a used servo before buying a new PCM.
