3 Answers

My 98 ply gr voy interior climate control, rear wiper, ac indicator lights flash. They will stop after van runs for about 45 min. Disconnecting battery does not resetthem. My radiator fan will not work and I overheat. Replaced fan coil relay, new radiator fans (2) ECM and verified my temp sensor is working. I see no blown fuses.

    I am capable of electrical trouble shooting if I know some details. I verified the harness connection is ok from tempeture senser to the next harness connection. I tested the line from I believe the new fan relay coil to the radiator fan motors and they read contenuiety, indicating to me there is a short out of the fan reley coil which matches the code P1491. So the connection at the fan reley coil must be the bad area and I know the plastic was briddle and broke outside case. It still connects tightly. If a tech there is familure with electrical connection and can send me a sketch we can find and correct this.

    Also is this error connected to what is wrong with my blinking temp. control /rear wiper control lights ? Because my blinking indicater lights clear up and stay lite after driving or running motor for 45 min

    my 98 ply gr voyger 3.3 litre engine has a service engine soon light. It is overheating because my radiator fans will not come on. My wire harness is not grounding out leading to the fan coil relay. The connection to the fan unit shows a closed circuit which I think should be open. I been reading some of the posted problems and wonder if the blinking lights on my temp control and rear wiper control can cause this to malfunction. My blinking control panel will stop and light steady like normal (if the item is on) after running vehicle for 45 minutes. That indicates to me there is no short in my control panel. I also read there may be a issue with my BCM (Body Control Modual). Note i have replaced my fan coil relay, fan unit, and ECM. Can you walk me throuigh more testing and what to look for? Is there any wire diagrams that you can email me? Anxious to get this vehicle working correctly

    My 98 gr voyger is a 3.3 L engine not a 3.0 Can you send a wire diagram for the correct engine

  • Paul Aragosa Jun 07, 2011

Your next step should be to replace the BCM, or body control module. Under the dash, to the left of the steering column. If I remember correctly, it is on the rear of the fuse panel, just above the parking brake pedal. This contols the functions you are talking about. in fact All the electical system of the vehicle, except for the engine and transmission, are mediated by the body computer module. This means that instead of hard wiring many components together that sense and respond to one another, they send and receive instructions through that computer. This allows for more complex behavior and reduced wiring. Before accepting a recommendation for replacement, there should be proof that it is faulty. With a proper test tool the computer will issue a fault code that says it is faulty, you shouldn't have to guess about it. There is a manual that covers the body computer and which gives procedures for problem-solving short of replacing the computer. Until those procedures are followed and unsuccessful it may be fruitless to replace it. It is located in the cabin, under the dash, on the backside of the fuse panel and is electrically connected to it by sliding them together so that terminals mesh together.

The problem is most likely be related to the wiring. I would suggest to have the wiring harness inspected. A visual inspect inspection is needed. What you are looking out for are loose wires or wires with bad insulation, exposed copper or terminals which are bad and may need cleaning.
Heat affects electrical devices especially the conductor. After running a grounded wire may have difficulty conducting electricity due to the increase in temperature. Vibration also affects this especially if it is a loose wire issue and problem may appear intermittent depending on the nature of vibration.

OK got your message on the other post (About the van) I am assuming that your Voyager is equipped with Automatic Climate Control. Follow the instructions below and you will get a better idea of what is wrong with your system.

Calibration/Diagnostics
1. To enter calibration/diagnostics test, set parking brake. Start and warm engine to normal operating temperature. With engine idling, turn blower switch to high. Turn mode switch to panel. Open all outlets. Move temperature to full cold.
2. Press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (Until ALL LEDs illuminate). All LEDs should illuminate for 5 seconds. Rear wiper and intermittent rear wiper button LEDs will flash alternately during calibration/diagnostics test.
3. After approximately 60 seconds, if only the rear wiper button LED is flashing, calibration is successful and the system is okay. If rear wiper and intermittent rear wiper button LEDs are flashing, Diagnostic Trouble Codes (DTCs) are present. (See "Reading Diagnostic Codes" below)
4. To exit calibration/diagnostics test at any time, press the rear window defogger button, rear wiper button, or cycle the ignition off and then on. Test will automatically terminate 15 minutes after calibration/diagnostics is entered.

Reading Diagnostic Codes
1. Perform calibration/diagnostics test. If a DTC is present after calibration/diagnostics test has been performed, system will flash rear wiper and intermittent rear wiper button LEDs in sequence. Rear wiper represents code level, and intermittent rear wiper button LED represents code value.
2. Each time the rear wash button is depressed, rear wiper button LED wil cycle to the next code level in numeric sequence. After code level 5 is reached, rear wiper button LED will cycle back to code level 1. See table below.

Try resetting the system again by taking the negative cable from the battery, and them depressing brake pedal for 30-45 seconds.

Reconnect neg cable and see if it still does this.

Almost sounds like the HVAC system is stuck in test mode.

Blinking airconditioning lights


Hi there,

TO INITIATE TESTS:
1. Set blower to HIGH
2. Set mode position to PANEL (AC vent air)
3. Open all AC outlets
4. Temp. on full cold
5. Start engine
6. Push WASH and REAR WIPER switches for 5 seconds until all panel lights are on solid
System will then go through it's paces as it calibrates the climate controls
7. When calibration is complete only the REAR WIPER switch/light should be flashing. Press this switch to extinguish the light
This will stops blinking lights.....

Good Luck!!

Thanks
