1990 964 heater fault.....HELP
 

I have a 1990 RHD 964 C4 that the air to the windscreen only blows on the left hand side and nothing on the right side and get no air to the left side going to the feet but the right side is OK.
The flaps are working for the air going to the feet as I have had both the vent trunks off on the weekend.I dont get hot or cold air out of the ones not working.
It looks like a big job getting the heater assy out and dont want to do that it I dont have to.I cant find any manuals that help me.

Can anybody help please..................

sounds like the servos just behind the fuel tank..... try p-car.com

mines the same
 

Not certain which of yours is doing what, I personally
don't see anything moving when key is switched on, although I can 'hear' air being directed this way and that, as I alter controls.

I popped off cam on the number 5 servo?
passenger side, and manually directed the heat to that whole side
while I wait for someone to fix it properly

anyway see here
