No Heat from blowers
HI All,
Was driving the vette last weekend when it was a tad chilly over here in England and for the first time tried to increase the temperature. Even with the top setting there was still no heat from the blowers. Anyone have any ideas, is this a common problem with the C4? Mines a 1990 facelift interior.
I really don't like all this climate control crap. I'd much rather have a **** or lever for temperature and a button/slide for the fan speed. Nothing but problems with these expensive climate control units.

It sounds like your blend door is permanently in the low temperature position.
Take the blower control module out of the evaporator housing and look at the blend door after you set the temperature to 90°. It should look like this:
If it looks like this:
then either your blend door motor is bad or the HVAC programmer (above the gas pedal on the firewall) has a problem.

Ah Right, thanks for the info. I'll look into that when i get a bit of time.
As i'm a total novice, Can you tell me where the blower control module/evaporator housing is located?
Is it easy enough to do? I know in the Supra it was an absolute bitch and a garage wanted over £1000 for the labour alone
