Strange................
 

Hi Newbie here. (1995 993)
Has anyone else had this happen?
On starting the car, in the morning, the fan switches on and operates in fits and starts. All heater switches are off. This doesn't happen after the car has been stood all day, just in the mornings.
The fan stops after about 20-30 seconds.
Any ideas?
Thanks in advance.

Climate control modules were known to go bad in the 993's unfortunetly.

Where is this Control Climate Module located?

RE: Strange................
 

Well, it is the control unit that has your fan knobs, ac button, defrost button, etc. Though you won't like the price of a new one.

I've been offered a unit $350 plus shipping, still in it's box!

Another question Doc, Is it OK to still drive the car with this problem or am I going to damage something else?
Thanks for the advice.

OK, there’s some additional information on my problem.

Last night, on switching on the ignition the erratic fan thing happened again, and then I heard some ‘clicking’ from the engine compartment. I left the ignition ON, lifted the trunk and saw the ‘Rear Shift Valve’ operating. I wasn’t in reverse gear so this valve shouldn’t be operating. My ‘Essential Guide’ states this valve supplies a ground earth to the CCU.

Is this making any sense?
