Weird Heater-A/C problem...
Howdy All,
My 300D environmental system has been freaking out lately. When I select the AC or vent positions on the switch panel, the fan and A/C pump click on and off. If I select the defrost position, the pump and fan work fine.
It started about a month ago when I noticed a lot of clicking from the dash in the switch area.
Is there a relay or controller going bad or a ground problem here? I wonder if anyone has experienced this issue... There seems to be a thread here for just about every problem imaginable for this car. If I ignore the clicking and fanless heating for a while, it works normally.
I don't have time to troubleshoot all the electrical connections, so hopefully this is a common thing. I trust you guys to have some kind of horror story for me...
Thanks,
Kevin

...Threw money at it.
Howdy all,
I fixed the problem with a used climate control unit from eBay. $25.00 and everything works again.
A simple fix for an annoying problem...
