Have a 98 996 C2 Tiptronic.
Recently had a new air con condenser and rad fitted and the system re-gassed (air con hadnt been efficient for around a year) and now blows cold air perfectly in time for the winter [8D]
One thing I have noticed is that there is a noise, apparently coming from behind the dash - a kind of whining motor type noise which increases (i think) with fan speed so now leave the fan on minimum or just off.
I tried turning off the air con button whilst leaving the fan on and the noise goes away so its something to do with the air con for sure.
Before I bring it back, could this be a gassing problem or any other ideas? A coincidence or is the noise likely to do with the recent condenser change?
Thanks in advance,
Rob
