Had a blown relay,
I unhooked the positive battery terminal, with a phillips screw driver took the fuse block under the dash loose. Checked the relays with an ohm meter, replaced the bad one. presto it works.

thats all folks.. pardon the humor

SOURCE: major power window problems. 2000 pontiac bonneville

I had this problem where only the drivers door power equipment works.

It is caused by a splice under the driver's seat. Spice #S302 where the input from the drivers door module to the other door modules connects. It is one of those cheap *** splice that should be outlawed. Moisture gets in it and corrodes. Cut back the wires till you get the good stuff and redo it the right way.

Splice S302 can be found under the carpet about six inches before where the wires go up to the drivers seat. It is in a plastic wrap and tape. I believe the wires for the window are brown and white.

SOURCE: 1999 gmc jimmy power windows locks mirrors wont

If none of the mirrors or locks work, then you will very likely find a blown MIR/LCK Fuse #7 (10 Amp) in the underhood fuse block. If this is the case, you need to find out WHY the fuse blew because if you simply replace it, it will most likely do it again. Otherwise, the locks and mirrors also connect to the Body Control Module (BCM). I would recommend scanning the BCM for fault codes.

The windows are a completely separate circuit. They have nothing in common with the mirrors or locks other than than that they all ultimately get power from the battery and the circuits run through the umbilicals that go between the body and the doors.

If none of the windows are working, the most likely cause is an open power circuit or open ground circuit at the driver's door. This could be either a bad master control switch or is could be that the wires inside the umbilical are broken (fairly common).

I have a 1985 travelcraft motorhome. It says..econoline 350 ford. But the vin isn't matching the year? I cant find anything about this model. I'm trying to make it legal. We just bought it..any...


The only part of the motor home that ford provided was the cab and chassis. the 10 didgit in the vin number denotes year of vehicle. the vin on the dr door should match the vin on the dash.
letter b=1981 c=1982 d =83 ect the rest of the motor home is manufactured and installed on the open chassis. I hope this helps

Fuel Pump, power seats, windows and mirror all stoped working at


You might want to check the battery cables and if there is a smaller chassis wire from the battery. Clean these. It sounds like you lost a ground wire somewhere and it is trying to ground through any wire it can find.

Electric Mirrors do not work (Drivers & Passengers)


There are two power wires to the DDM - drivers door module .Both are orange ,one is powered by a fuse DDM fuse 15amp . in the left I/P fuse block , plus LT DOORS 25amp circuit breaker .
Power Mirror System Components
The power mirror system consists of the following components:
• The driver door module--Class 2 module with integrated switches and requires programming when replaced
• The passenger door module--Class 2 module with integrated switches, requires programming when replaced and also contains the RFA receiver
• The power mirror direction switch--Integrated into DDM and is a 4-position momentary switch that provides a signal input to the DDM for up, down, left/extend and right/retract with a mirror switch activation
• The mirror select switch--Integrated into DDM and is a 3-position switch that allows the operator to select the left or right mirror and also a neutral/fold position
• The left outside power mirror--Contains both the vertical and horizontal mirror motors and is serviced as a complete mirror assembly
• The right outside power mirror--Contains both the vertical and horizontal mirror motors and is serviced as a complete mirror assembly
• The body control module--Class 2 module that requires programming when replaced, serves as the power mode master and is the main message handler
• The DDM 10A fuse--Located in the I/P fuse block and is hot at all times
• The PDM 10A fuse--Located in the I/P fuse block and is hot at all times
• The memory switch, if equipped with memory mirrors--Supplied power by the DDM and provides a voltage signal to the DDM upon a switch activation
• The horizontal and vertical position sensors, if equipped with memory mirrors--Supplied a 5-volt and low reference by the DDM/PDM and provide a variable voltage signal to the DDM/PDM that is proportional to mirror position
• The park neutral position switch, if equipped with memory mirrors--Provides transmission gear selection information to the PCM and is used for memory recall and mirror tilt in reverse functions
• The powertrain control module, if equipped with memory mirrors--Class 2 module that requires programming when replaced and provides Class 2 message indicating transmission gear selection
• The driver information center (DIC), if equipped with memory mirrors--Part of the instrument cluster which is a Class 2 module that requires programming when replaced and is used to personalize the memory recall and mirror tilt in reverse functions
• Fold motor in each of the outside mirrors, if equipped with power fold mirrors--Provides extend and retract movements of the mirror and is serviced as a complete mirror assembly
Each of the outside power mirrors contains 2 reversible motors to provide horizontal and vertical movement of the mirror glass. The vertical motor operates the up and down directions and the horizontal motor operates the left and right directions. If equipped with power folding mirrors, each outside power mirror will contain a reversible fold motor to operate the extend and retract functions. Each of the mirror motors are circuit breaker protected.

Do you know what DTC'S are ? Diagnostic trouble codes
DTC B1544, B1600, or B1605
DTC B1580, B1590, B1610, or B1620
• If DTC B1580 is set by itself, the left horizontal position sensor signal circuit maybe open, shorted to ground or battery
• If DTC B1590 is set by itself, the left vertical position sensor signal circuit maybe open, shorted to ground or battery
• If DTC B1610 is set by itself, the right horizontal position sensor signal circuit maybe open, shorted to ground or battery
• If DTC B1620 is set by itself, the right vertical position sensor signal circuit maybe open, shorted to ground or battery.
• If DTCs B1580 and B1590 are both set, the left 5 volt reference or low reference circuit(s) maybe open, shorted to ground or battery.
• If DTCs B1610 and B1620 are both set, the right 5 volt reference or low reference circuit(s) maybe open, shorted to ground or battery.
Need a factory scan tool to test !
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, observe the mirror horizontal and vertical position parameters in the Driver Door Module (DDM) and Passenger Door Module (PDM) data lists.
Operate both the left and right mirrors through the full range of movements.
Does the scan tool indicate that the left and right mirror horizontal and vertical position parameters are within the specified range?
0.50-4.75 V.
Your best bet , take it to a GMC , Chevy , buick or cadillac dealer

1999 windstar- non functional windows, cruise, radio


Looking at a wiring diagram ,the BCM has nothing to do with the cruise control . This vehicle has two different body control modules ,the (FEM) front electronic module an the (REM) rear electronic module . The power door locks are controlled by these two modules . The door lock switches are inputs to the (FEM) . The driver door lock is also controlled by the (FEM) . The right front and the rear door locks are controlled by the (REM) . The power windows are not controlled by these modules ,so it is not a faulty body computer . An where did you check codes ? Takes a factory or professional type scan tool to read these codes . No code reader , they just check PCM - engine codes . The power mirrors are not controlled by these modules either . Nor is the radio .
Looking at a wiring diagram i see the power mirror's and the power window share a common ground point G-305 , so does the rear radio controller ! (if your vehicle has one )
Buying an replacing parts is no way to fix these problems ! Using a wiring diagram and a DVOM - digital volt ohm meter to test the electrical circuits of these systems is the way to find the problem . Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Then under system click on body an Accessorys , subsystem click power windows . Check for B+ voltage to the master window switch , check for a good ground .( Loaded circuit test ) Do you know what that means ? Watch these videos !
