High setting on HVAC not working 1990 300SE
Hello All,
I have a 1990 300SE with 236,000 miles and the high speed fan for AC and head does not work.
I took apart the HVAC controller and re-soldered all the joints. Still not working. Any ideas of what the problem could be?
Thanks in advance
Dan

sleepwalker,
I think the temp switch is OK as the automatic temp does work to control the heat or AC. I the resistor(s) was bad wouldn't I just have high speed and not low?
Thanks for your help
