when I turn on my fan it works in all modes except high, I have been told that a connector is at fault b/c it melted, he says all th GM cars he wrorked on had this problem, can you verify it?? And he says it is under the hood where the wiring goes through the firewall, where can i find this?

 

hey mine is like that on my S10, just thought i would note that..

ok, so it just might be a GM problem and not the jacka$$ who put a system in my car and ****ed with the wiring....

 

no i think it might be the jack *** . because mine didnt do it till after i pulled the assembly to change the lights behind the dash, so i know i did it, but i dont care about that vehicle so it doesnt matter!

Check the high speed blower relay near the fan, under the hood.

would that have a little blue fuse next to it?? On the drivers side??

 

no it would be over by the fan motor. also check to see if the relay is even getting the high load power. not the wire that does the switching but the wire powering the fan. Should be a larger wire going to the relay. My 89 camaro did the same thing and i traced the wire back to a sh-ty connection. i reworked the connection and it worked fine ever since.
