When I first turn on the heat in my Carrera, the heater motors scream, what can I do? They stop screaming when the car warms up. Maybe they need oil or a grease job. Please help,

My SC had this exact same problem, then last weekend the fan stopped altogether!
I've not had a chance to have a look at it yet but any advice would be most helpful.

I think you'll find it's the bronze bushings for the shafts. What will happen - eventually - is that it will get worse, and then the blower will stop all together - blowing the fuse in the left side engine fuse block. Aside from reinstalling the housing bearing - replacement is the only solution. There is an "aftermarket" blower fan which apparently works - but I don't have that link..?
Anyway - it's a very common problem.... I think I went through 3 blowers in 8 years on my '87 Carrera - but I did drive it year round....
Wish I had better info for you!!!

They are behind the panels on the left and right sides of the footwell, just forward of the doors. The panels come off very easily - 2 or 3 screws - and the motors are right there. Also very easy to remove them for service. I've lubed mine several times and they always start making noise again. The hvac motors on these cars are really lightweight and not very durable. I've replaced all of them (fresh air motor, a/c blower motor, a/c condensor motor, and engine compartment motor) in my '88, except the footwell motors where I just gave up and pulled the fuses. The heat that's blown forward by the motor in the engine compartment does a good enough job. You have to wait for the engine to warm up to get any heat anyway, so before that you're just blowing cold air. The footwell blowers probably do help with a faster windshield defrost, though.
It still amazes me that in a car where the designers have gone to great lengths to reduce weight and make everything reliable, they used 6 cheap, heavy motors where 2 or 3 really good ones would have done the job.
