I hate to sound dumb, but have you replaced the multi function switch also? Do your wipers only work when you press the wash button?The Multi function switch is the actual wiper/bright control/turn signal switch. They go bad often in these models, I have a 96 town and country (108,000 miles and still love it) and have had the same problem.I have also heard of taking the wiper motor apart and cleaning the contacts (which I did, to no avail). I first started with the multi function switch, went on to the wiper motor and I cleaned (scraped) every electrical contact that has to do with the wiper, I pulled the BCM and checked for any cold solder joints, and I am currently waiting for my ordered new BCM and I hope that is the problem.

WHERE IS THE WIPER/WASHER FUSE LOCATED ON 2007 PONTIAC TORRENT


In the under hood fuse box , should have diagram inside the lid . Front wiper's or rear ? Front fuse # 36 - 25 amp. Plus Two relay's PCB hi and Wiper PCB relay . Wouldn't think this being fuse problem . Wiper switch , motor etc... The wiper's are control by a computer . BCM - body control module .

The windshield wiper/washer system consists of front and rear wipers. The front and rear wipers are operative when the vehicle is in accessory or run. The front wipers have 4 different modes: Mist, Intermittent, Low, and High. When the front wipers are in the intermittent mode, there are 5 delay modes to chose from, commanded by the windshield wiper washer switch through the body control module (BCM). The rear wipers has an only one mode.

If the fuse is bad , could have a short to ground or wiper motor pulling to much current (amps) . Fuse's don't just blow for no reason ! Could also have DTC'S - diagnostic trouble codes stored in the BCM .

DTC B3873
DTC B3875
DTC B3922

DTC B3715 02: Front Wiper Relay Drive Circuit Short to Ground
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation.
The BCM controls the windshield wiper motor through two output controls, controlling two different PCB relays which control the desired wiper speed, high or low.

The PCB relay's are non- servicable , replace fuse box . Soldered in Your best bet mit be to take it to a qualified repair shop .

Why don't windshield wipers with rainsense work?


No wipers at all , hi , low , delayed ? You really need a factory scan tool to diagnose this problem , there is a lot involved ! The switch , BCM , wiper relay , an wiper hi relay ! With a scan tool you would be able to access data parameters in the BCM - body control module . When you turn the switch to turn on the wipers , that's an input to the BCM , the BCM then energizes the proper relay in the under hood relay box . Turning on the wipers ! Plus there could be trouble codes stored in the BCM pointing to a problem .
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through a resistor internal to the switch and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WPR relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WPR relay and out to the switch input side of the WPR HI relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the WPR relay can also be commanded ON/OFF by using a scan tool. Refer to Scan Tool Output

The windshield wipers on my 2001 Chevy Venture wont work in the "delay" positions...could this be a fuse/relay problem?


Most likely a little circuit board that controls the wiper delay, or the wiper switch itself has gone bad and has an intermittent break.

Front windscreen wipers, speed control doesn't always work, wipers can take a very long time to start. Can the wiper relay be replaced in the CCU be replaced or replace the switch first?


Not sure what model vehicle your working on, but some have a circuit board near the motor it self that tells the motor the speed and delay commands. I would check that first

2007 HHR Has no power, replaced shifter assembly, still no power.


Check all main power feeds to all fuse centers (boxes) ! Do you know what a electrical distribution diagram is ? How to use a DVOM - digital volt ohm meter to test electrical circuits ?
Has no power, replaced shifter assembly ???? No power where ??? And why would you replace shifter assembly ???? What happens when you turn the key to on ? not start ,just on ? Insturment cluster lights up ?
Is the battery good ? Connections an cables ? Your going to need to check power at the battery ,fuse boxes etc.... Confirm there is B+ voltage somewhere !
Your best bet , take it to a qualified repair shop . You have no idea of the complexity of this vehicle ! Everything is contolled by computer ! The ignition switch is a input to the BCM - body control module , by these inputs the BCM will control the vehicle .
The body control module (BCM) has a bussed electrical center integrated into the housing. Body control relays and fuses are installed directly on the BCM, which simplifies wiring and junction blocks on the vehicle. The body control system consists of the BCM and its associated controls. Battery positive voltage is provided to the BCM from IBCM BATT 1 fuse and the IBCM BATT 2 fuse in the underhood fuse block. The module grounds are wired to ground G201, G203 and G305. The BCM is wired to the GMLAN High speed serial data buss, and the GMLAN Low speed serial data buss, as well as discrete input and output terminals to control the functions of the vehicle's body .
Serial Data Gateway
The body control module (BCM) in this vehicle functions as a translator between the High and Low speed GMLAN busses. The 2 communication protocols use the BCM to translate communicated serial data messages between the control modules over the 2 serial data busses.
Power Mode Master
This vehicles body control module (BCM) functions as the power mode master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.
Power to many of this vehicle's circuits are controlled by the module that is designated the power mode master (PMM). This vehicle's PMM is the body control module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.
Serial Data Power Mode Master
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The 3-wire Ignition Switch table below illustrates the state of these inputs in correspondence to the ignition switch position:

Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs Off/Run/Crank, Accessory, and ignition 1, to distinguish the correct power mode. The ignition 1 circuit is also routed to the Run/Crank relay for relay controlled power feeds during the appropriate power mode. The BCM, after determining the desired power mode, will activate the appropriate relays for that power mode.
Run/Crank Relay
The run/crank relay control circuit is connected to a constant ground and is switched by the ignition 1 circuit or the body control module (BCM). The BCM, will in lieu of the ignition switch position, activate the Run/Crank relay during a remote start event. The Run/Crank relay supplies a power signal to the following circuits, when the a Run or Crank power mode is selected:
• Automatic transmission shift indicator
• Automatic transmission (A/T)
• Switched power feeds to the BCM
• Electronic brake control module (EBCM)
• Electronic ignition module (spark control)
• Electronic power steering module (EPS)
• Fuel injectors
• Powertrain control module (PCM)
• Park neutral position (PNP) switch

Do yourself a favor an take it to a qualified repair shop !

What is the difference between an ECM and a BCM? Does a BCM have to be flashed?


The ECM (Electronic control module) runs the engine and the emission control system, the BCM (Body control module) operates most electrical body functions like wipers and interior lights and power windows and door locks plus the security system in may cases, the ECM (on this car now known as the PCM since 1996 by federal mandate) can be flashed, which just a reprogramming of the EPROM chip

1993 Dodge Dynasty. Wipers stopped working. Replaced fuse. Still not working. Replaced Body Control Module(BCM) located inside kickboard(passenger side). Still not working. Tried a second BCM, didn't...


BCM's are part number specific to your particular vehicle so unless you got from a dealer and had the dealer flash it for you none will work.

Caravan's had the same problem with their bcm's

Did you test the motor to see if it was working before you got the bcm's?

Did you test the wiper motor switch?

Also test the wiper motor relay.

I think you need to replace the Body Control Module (BCM), My newly replaced BCM (used) fixed my wiper problem but created a new problem which the left turn signal is not working now. Time to sell the van.

I had the exact same problem PLUS my power door locks and some guages stopped working. I replaced the Body Control Module (BCM) which is behind the inside fuse box and problem was fixed. I did get the part from a salvage as the unit from Dodge was $1000. Make sure you replace with same part number and disconnect battery before working on it. One downfall of changing BCM is I now have a new odometer reading.
