1993 Buick Century Q&A
1993 Buick Century Question: heater vents not working properly! rough idle after warms up.
Heater only blows air out the ac vents, when I put lever in the defrost slot, I hear the ac pump kicking in. is there some kind of actuator switch not working? I just bought this car, and I replaced both head gaskets and did a valve job as well, it ran before I did this but since it had a blown head gasket I did not let it warm up enough to know if the idle problem was there prior to tearing into it. when I first start the car, it runs as it should,(rpm's high until gets warmed some) then after it warms up some the idle returns to normal but it wants to die and sounds really rough. Any help would be appreciated. - 2doors
CHECK FOR VACUUM LEAK COULD BE CAUSING BOTH PROBLEMS. - pushrod
I would take it back to the shop that did the heads - goodguy
