Question about Cars & Trucks

Open Question

I can't find an electronics repairer for a duomat 5 electric bed motor operating system.

I've removed the motors, which is quite straightforward, and found that the motherboard has four solenoids on it, one for each direction of the two motors. They spark inside (seen through their opaque plastic covers) and only work intermittently. They need changing or need a new motherboard. Unfortunately they're soldered in. Any advice would be appreciated. Thanks. BRS

SOURCE: honda crv window motor not working

You will need to remove the bolts that hold the window guides in place, and carefully lower the window assembly so you can get to the bolts that hold the regulator to the window. When reinstalling, be careful not to over tighten the bolts.

SOURCE: 1987 volvo 244 intermittent fast idle floods after shut down

The coolant temp sensor sends signal to the ECU and the ECU adjusts the idle RPM. When the coolant is cold, the engine requires more fuel to sustain idle with thick oil (oil gets thicker & more viscous when cold). This makes the engine to idle at faster RPM but it should settle down to 850 RPM or so after the coolant warms up. The sensor is nothing but a thermistor; a device that changes electrical resistance according to the coolant temperature.

SOURCE: Need help removing power window motor on 1998 Ford F-150

You drill the head of the rivet out....start with a small bit and work your way up....then pop it out with a blow from a hammer and a screwdriver or punch. Then, if you don't have rivets to replace the removed ones, get a few bolts and nylon threaded nuts and use those to install the new window motor.

Sunroof will not close. Was working fine earlier today


The roof opening panel assembly uses an integrated motor and module to operate the roof opening panel. The roof opening panel motor and module are installed new as an assembly. The roof opening panel is an electronically operated glass panel that can be opened or closed by the roof opening panel switch. Actuating the switch in either a forward or rearward motion supplies a ground to the roof opening panel motor/module. The soft-stop function is controlled by the roof opening panel motor/module. The roof opening panel has 3 modes of operation, manual mode, express open and tilt. The express open feature is activated when the switch is pressed momentarily. The tilt feature is activated when the tilt switch is depressed. These functions are controlled by the roof opening panel motor/module.

Turn signals in my 98 Toyota Camry don't blink. And the the front passenger window doesn't work. Niether does the car lamp inside the car.


If just one window doesn't work, that is a separate issue, and probably a bad motor for that window. The inner door panel would have to be removed to investigate if it is the motor or a wire not connected.
For the radio and lights, all I could say is check the fuses.
For the blinkers try a new flasher. I've never heard this before, you must be pretty adept at it by now. Wiggling it to make it work means either the connection is poor or the flasher has a foot ******- Replace it!

Driver window quit working after car wash


It appears that the electric motor that operates the windows has become faulty after letting in water after the car wash. The motors are sealed with a gasket, but can some times let in enouh water over time to cause corrosion an prevent operation. To access the window mechaism and motor you will have to remove the interior door trim an then undo the necessary bolts to remove the window mechaism. Removing the end bell of the motor and alowing to dry and removing any corosion should get it working again if the motor has not been burnt out.

Aircondition blows hot air on normal but blows cold air on max


The temp blend door rotates between allowing heat through the heater core, or cold air through the a/cevaporator, or a blending of the 2 by being anywhere between the two.

I would check the heater a/c control head first and hope it's just the control head.
----------------
here is a descripton of the system.

Section 12-03A: Air Conditioning, Heater System, Manual, Ranger and Explorer 1996 Ranger and Explorer Workshop Manual
DESCRIPTION AND OPERATION A/C-Heater System, Manual The manual air conditioning/heater system used in these vehicles is a split-case, blend air design. This design includes the following major components:
  • An A/C evaporator housing (19850) which is attached to the engine compartment side of the dash panel (01610). This assembly includes: (1) the A/C evaporator core (19860), (2) the suction accumulator/drier (19C836), (3) the A/C cycling switch (19E561), (4) an internal, A/C evaporator core orifice (19D990) located inside the inlet line to the A/C evaporator core, (5) a blower motor (18527), (6) a blower motor wheel (18504), (7) a heater blower motor switch resistor (18591), and (8) the A/C evaporator case (19897).
  • A heater air plenum chamber (18471) which attaches to the passenger compartment side of the dash panel. This assembly includes: (1) the outside/recirculating air inlet door, (2) the panel door, (3) the floor defrost door, (4) the temperature blend door, and (5) the heater core (18476).
  • Other components which link and/or control the heating and air conditioning systems include: (1) the A/C control (19980), (2) the ducts and registers, (3) the windshield defroster hose nozzle (18490), (4) the control cables, (5) the vacuum lines, (6) the refrigerant tubes and hoses, (7) the A/C compressor (19703), and (8) the A/C condenser core (19712).
050240f.gif
The A/C control (19980) assembly consists of three main parts:
  • The function selector knob, a vacuum selector valve combined with an internal electrical switch.
  • Heater blower motor switch (18578), an electrical switch that provides four speeds of A/C blower motor operation.
  • A temperature control knob, which controls the position of the temperature blend door mounted on A/C evaporator housing (19850) assembly.
---------------------------
Temperature Control
The temperature selector actuates a variable resistance switch. This switch varies the voltage to an electric actuator used to position the temperature blend door. Positioning the temperature control in any position between COOL and WARM causes the temperature blend door to direct more or less outside air through or around the heater core (18476) for whatever proportion of heated or unheated outside air is desired. The air blends together as it leaves the heater core and enters the heater air plenum chamber (18471) for distribution.
---------------------------
System Airflow Description Air is drawn into the system by the blower motor (18527) through the outside-recirc. door opening. The air is blown through the A/C evaporator core (19860) and then the heater core (18476) (when the temperature control is moved toward the WARM position). When the temperature blend door is in the maximum COOL position, the air bypasses the heater core. When the temperature control is moved to the right, away from the maximum COOL position, air passes through the heater core where it is warmed, and then mixed with the cool air before it is discharged through the registers. OFF
With the function selector in the OFF position, the outside-recirc. door is in the recirculated air position. It is closed to outside air and no air passes through the system. The blower motor is off. MAX A/C
NOTE: No temperature modulation is possible in the MAX A/C position.

In the MAX A/C position, the outside-recirc. air door is in the recirculated air position. All of the air discharges through the panel registers except for a small amount of floor bleed. The A/C compressor (19703) operates in this function control setting.
--------------------------------
You have to almost remove the dash to get this part out.
Removal
  1. Disconnect battery ground cable.
  1. NOTE: Refer to Section 01-12 for instrument panel removal and installation procedure.

    Loosen instrument panel (04320) and pull back from cowl.
  1. Remove A/C electronic door actuator motor electrical connector from bracket on A/C evaporator housing.
  1. Remove three A/C electronic door actuator motor retaining screws.
  1. NOTE: The mounting bracket remains in place on the A/C evaporator housing.

    Lift A/C electronic door actuator motor vertically approximately 12mm (1/2 inch) to disengage it from bracket and actuator shaft, then pull A/C electronic door actuator motor back toward passenger compartment.

Abs light is on


Locate and pull the ABS pump fuse located in the power distribution center under the hood and CHECK IT TO SEE IF THE FUSE IS BAD. Basically you are looking for a fuse box with large amperage fuses and some relays. Look along the fender well in the engine compartment relatively close to the battery. It is a 60 amp fuse in most instances and should be clearly labeled "ABS" in the large fuse box with other similarly oversize fuses used for other high power subsystems. 
 All ABS systems are designed so that the solenoid valves in the ABS brake manifold are in safety "bypass" mode when powered down or when the ABS control module has been removed. You will have standard everyday power brakes no different than brakes built without the ABS system.

The ABS system will perform a self check once you exceed 5 MPH and the "ABS" and "brake" lamps should turn off. During this test, the controller runs the pump motor and briefly operates all of the valves. This ABS "self-test" is performed every time you start and drive.

EBCM is short for "Electronic Brake Control Module" It is the advanced computer than controls the electric motor pump and valves of your ABS system.  Burnout of the motor is very rare however. A MOSFET transistor in the EBCM (Electronic Brake Control Module) has failed, can cause the pump not to perform.

Pump motors generally do not fail, but when they do, the culprit is usually worn-out brushes or corroded electrical connections. In a worst-case scenario, your motor is beyond repair. It is bolted directly to the hydraulic assembly- a cast aluminum brake fluid distribution hub with 5 or 6 brake lines branching off of it and wiring harness.

I hope this helps before you get your hands to dirty. In short check all the electrical connections first. Try running a hot wire to the pump motor first to see if it runs and if it does, then it's not the motor and could be a easier fix by changing the (EBCM).
