Do me a favor and check the voltage going to the RR HVAC fuse.. what's it at ?

Running down the power side seems like the logical conclusion. I really don't want to start arbitrarily ripping into the overhead.

Do you know where all the remaining components in the circuit are located?

Also, if it help with diagnosis, my wife told me it worked intermittantly before it died completely.

Did you check the voltage at the RR HVAC fuse ? If so, what was it ?

I must have missed the first question about the voltage at the fuse.

Again, with motor running, fan on high.

Across the fuse terminals (with the fuse removed) 10.5 V.

From fuse to battery 13.5V.

The fuse visually looks good. Corfirmed with a resistance check.

Ok, here is where C206 is.. number 19... this is a diagram of instrument panel. If you go behind the LH kick panel, you should see this connector..the picture on the very bottom of this post is a diagram of the connector.. you want to go A6. From here you can test to see whether the problem lies between the fuse block and C206, or between C206 and the resistor pack. The connector is light gray, and has 22 cavities.. terminal A6 should be an orange wire. also, the diagram of the connector is the female side.

C397 is above the blower motor and looks like this: again, this is the female side.. and you want terminal A, which should be an orange wire

i found the problem!!!

pin A6 is burned. melted plastic on the connector and everything!

I am going to see if i can clean it up unless someone has a better suggestion.

Nice. What you should do is test, if possible, in the wires.. also check for corrosion on the terminal. Your best bet might be just do replace the terminal. By the way, did my diagrams help you ?

By terminal do you mean the electrical contact within the connector?

I have already popped the contacts out of the connector and I think they are beyond refurbishment. I'd bet there was some contamination from new and it took this long to become a problem.

If the individual pins are available, I have the tools to replace it.

My other option is to simply get a 25A rated connector and jump this wire in parallel with the main connector.

The dealer should be able to match them up.. I would replace both the female and male ends to be safe.
