Wow, thank you so much for putting so much time in my question. I really appreciate it.
Now Im not sure exactly which parts are what.
What part is the fan selector unit and where is it?
I do know what the resistor is as I had to help install it!
I haven't heard about the condensor yet, what is that and where and how does that relate to the heat? (okay stupid ?s I know)
Let me see if I understood you right. You are suggesting that the blower resistor was the problem in the first place right? I do believe that was the case two years ago. But after running it like that for a couple of years it burnt all the wires at the resistor. We had that replaced. The mechanic friend said the problem is somewhere between the two fuse boxes. He suggested that a wire could be the problem but then thought about changing the relay. Does the relay stuff make sense? I am going to check my Haynes manual right now for the heating diagram but I swear I have looked at that umpteen times and only understand a 10th of it.
My mechanic friend did check the fuse with a meter. It was a different friend that eyeballed it before. If I tried to eyeball the fuses I wouldn't know what the heck I was looking at. Thanks for the advise though. I would like to get one of those meters as it looked pretty handy to me. Again, thanks for all your help. I am willing to try anything. :flash:
