I am helping a friend fix his climate issues.

His first complaint was that the AC stopped working. Actually the fan had stopped working the AC compressor was running and the line was frosty and cold. The blower motor was not receiving power so I changed the fan speed resistor, and changed the very clogged filters. Everything started working but the fan was intermittently stopping. Well the fan connector was fried and melted and blew the 40A fuse in the engine bay. Changed the fan and replaced the fuse.

Now the fan is on full blast even if you try to shut the climate system off and the AC compressor will not engage so the car only blows hot full blast the whole time the car is on. The fan relay is good, I pulled the relay cover and watched it disengage when removed from the fuse panel, so it is receiving its on signal from the controller. I pulled all the fuses and the battery to try and initiate some kind of reset without success.

The 88 screen has a dash under the second 8 which indicates a resistor problem which I don't believe because it is new.

I believe that the fan motor running hot enough to blow the fuse may have damaged the digital control panel.

Before I spend any more of my friends money, I want to know if this is a logical, or if someone else can point me in another direction.

Thanks for any help.

 

Moving to correct model specific forum. You'll get more help here.

 

Thanks for moving my post. I have put it in the wrong place because the car is actually a 2000 TL. I couldn't edit it because I didn't have enough posts yet.
