Hi all, I have review a couple articles, however did not view my difficulty precisely. The air conditioner and warmth wont blow out the vents in my automobile. The fan is running and also a small air comes out almost everywhere. I replaced the blend door actuator and very same problem. Also, the air conditioner wont work-related. The clutch is not engaging. I do not understand if it is associated or a separate difficulty. The wiring looks okay the compressor, and also the relay is good (I switched it through the working horn relay) still no directed air. Any help would certainly be appreciated. By the method, if I have an actuator, carry out I still have vacuum lines doing things? Also, it is dual climate manage. Thank you.
I carry out not recognize why you would certainly readjust a blend door actuator for a difficulty through the mode door. The blfinish doors manage temperature, not mode. Tright here will be two vacuum mode door actuators on the left end of the HVAC housing. Check the vacuum supply lines coming from the engine and make sure that line is not leaking and has complete engine vacuum in it.
I carry out not have one for your exact automobile, yet right here is a basic picture of what vacuum actuators look prefer. Your car will have two, one for defrost and also one for other modes.

It is feasible for actuators to be negative however the even more widespread concern is lost vacuum in other places, The finest means to find this is to actually cut the line coming from the engine and also measure the vacuum and also then usage a item of tight fitting vacuum hose to splice the plastic line earlier together. There is a plastic vacuum storage tank that is also a widespread reason of lost vacuum.
Tright here is a rubber elbow coming out of the firewall just right of facility. It is attached to a half inch hard line in the fire wall and also is necked dvery own to a little dimension. Tbelow is nopoint plugged into it. I am having actually trouble seeing anypoint dangling about. I will store searching, appears prefer a most likely suspect.
Hey Mike, Yes inspect the vacuum source to make sure the heater air conditioner system is gaining vacuum at the selector valve behind the regulate panel, the valve itself can autumn apart and also you could hear a faint whistle.Let us recognize what you findBest, Ken
