964 "Blowers"...'90 C4 Cabriolet

[fleetline51]

I am still searching to find out why my ventilation system is not working...

I already pulled the CCU and servo-amp...did not find anything noticeably wrong(no cold solder joints,no poor cable connections,etc.)

I'll pull the CCU again and check the fan switch itself.

Speaking of fans...I know the left and right cabin fans run because I jumped them out at the amplifier connector...Same with the oil cooler fan and the engine compartment fan...Where is the "final stage blower" and the a/c condenser fan blower?

Are there any other fans or blowers hiding out that I should be looking for?

If the air sampler SENSOR is damaged or otherwise inoperable,might this cause the "no fan" syndrome?

If I get the cabin fans to run by jumping them out and turn the a/c switch on to activate the compressor(I can hear and feel it kick in when I do so) should I be getting cold air out of the vents? (or anywhere else for that matter?)

Hope You folks excuse the rhetoric...I'm tryin' like he!! to get this a/c - ventilation
system" un- freaked "

Thanks again!

Best Regards, Tony

In my 965 I have a blower motor in each fender and two in the luggage compartment that blow air into the cockpit. Wow, six blowers, seven if you count the turbocharger...
