I do have 14 volts on the battery side of the fuse. I also have 14 volts at the blower and radio fuse. I wasn't checking it right before. This time I checked from the fuse to the negative battery post.
Check connector C397 (shown in picture below-10,11) Test the orange wire for power in this location. Let me know what you find.
I only have 1 other connector. The orange wire goes to this connector and then up into the roof. I am not getting voltage here.
A common place for wiring problems to occur is under the fuse panel itself. Remove the brace at the rear corner of the engine compartment to gain access to remove the cover from the fuse panel (clips in place) Raise the fuse panel and inspect the orange wire under the fuse panel coming from the RR HVAC fuse. Rodents like to crawl up under the fuse panel and chew the wiring. Let me know what you find.
I had already done that and everything looks good.
There is another connector behind the passenger side of the dash. The service manual is unclear as to whether this connector can be accessed from under the dash. It is connector C206 (#9 in picture below)
Can I get back with you tomorrow evening? I will see if I can find that connector and check for power there. Roger
Tomorrow will be fine.
I found some connectors in the side panel by the glove box. One of the connectors has 6 pins with only 4 wires coming out of it. One of those wires is a big orange wire. I am getting 13.8 volts here. It could be connector 14 or 15 in the schematic. I go to the back and pull the 4 pin connector out of the resistor and plug in my voltmeter and I am getting 2.5 volts. I begin messing with the wires, untaping them and so on and the voltage is fluctuating and then all of a sudden I am getting 13.8 volts. I have the control on high speed and I plug the 4 pin connector back in and the fan comes back on temporarily. I jiggle the connector and the fan goes on and off so I am figuring that this connector has a bad connection. Then the fan won't do anything. I check the voltage and I am only getting 8.2 volts. Any ideas.
