Replying to: alphawolff (Apr 22, 2009 6:20 pm) On the frontside, are some connectors and some relays. Get down on your back under the dash. The integration relay is on the bottom, and then there are three relays right above the integration relay. The power relay, is the one on the left. Power feeds for the window control circuitry are: -25A door -10A Gauge -30A Power and the integration relay is involved, turning on the power relay, which then allows the 30A fuse to supply it's power to the door switchs.

Replying to: alphawolff (Apr 23, 2009 3:22 pm) Great, you are going to test it. Let me give you the info. The pins are arranged in a T configuration, T rotated 90 degrees counter-clockwise from how it normally prints, which is how you took it out of the socket. Pin 1 is the + of the primary coil, which turns on the relay. Pin 2 is the Grnd of the primary coil. Pin 5 and 3 are the secondary points. Pin 5 is connected to the output of the 30A fuse, and Pin 3 is connected to the window switches. 1 ## 5 ## 3 2 In case you don't know, when relay is engergized, there should be zero resistance from 5 to 3. When relay un-energized, should be infinite resistance 5 to 3. |

Replying to: kiawah (Apr 23, 2009 4:22 pm) Thanks again. The relay bench tested OK. There was zero resistance when the coil was energized. Additionally, since all 3 relays were the same, I rotated them all. Windows still don't work. As I said before the electric door locks are working, so any device that is common to both systems can be ruled out. I measured the voltage on the connector to the Master window switch. There is no voltage on pins 10 or 11 on the connector which, from my interpretation of the electrical schematics provides power to the Master window door switch for the windows (the ignition was on). Any further help you can give me would be appreciated. Bob

Replying to: alphawolff (Apr 23, 2009 4:44 pm) Since the Door locks are working, then the 25A Door fuse and 10A Gauge fuse are undoubtedly okay. At this point, i would suspect the integration relay is bad. But verify that your door courtesy switches (Front Left door, front right door) are working.

Replying to: kiawah (Apr 23, 2009 4:22 pm) One more thing. Although I tested all the fuses before I went back to double checkthe three specific ones you mentioned. I clearly found 2 of them and they tested OK. The only one I am a little unsure of is the 30 A power fuse you spoke of. I only found one 30 A fuse in the whole car, in the drivers side fuse box in the engine compartment. It wasn't clearly labelled but it tested OK. However, my schematic (from a chiltons manual for this car) represents this device with a unique symbol. Could this be a circuit breaker? If so where is it located? If not is the 30 A fuse you referred to in the drivers side fuse box in the engine compartment? Thanks again for all the free advice.
