Hi, I have a 95 seville and the ac only blows cold through the passenger side vents, it has the climate control for both sides but I only get cold through the passenger side.
I was wondering if there is a sensor or solinoid or something that is prone to go bad on these cars,or can anyone point me in the right direction as to what it may be?
Would apprieciate any help
Just to make sure, are the vents open?? The little slider thing could be broken, so you may want to investigate that. Does it blow air through all vents. IF so, im sure some solenoid or blend door is stuck....
Thanks for the welcome,
The vents are working fine, it blows just as hard as the other side and but not cold, also all the different positions such as floor,def,vent and floor etc work fine as well. It has to be something electrical, I think , I will check for codes asap.
All of the vents blow air (so a bad blower is out of the question), but it doenst blow COLD AIR out of the driver side vents.... I assume the defrost, floor vents, passenger side dash, and rear vents ALL BLOW COLD air. The only ones that dont are the driver side dash vents. Correct??
Thats really weird..... I think its some sort of mix door problem, but im not the technical person. Hopefully KATSHOT will see this, he will know the problem....
I'm not going to doubt that, but it doesnt make sense.... I think there is only 1 evaporator, and if it blows cold on the other vents. There MAY be more than one, so dont take my word for it.....
Ok, Ok. I've been off for the weekend and away from my tech manuals etc so I didn't want to say anything before checking them. Unfortunately, they don't have a lot of "easy" info for this system. It appears that there is one blower motor and one evap. However there are a couple heater cores and seperate blend doors and actuators for ducting. If the master control panel is in "DUAL ZONE" then the blend door is "split" and sends some air to the passenger and some to the driver/rear seat. That's right, the rear seat gets to share with the driver. The way I'm seeing it, there are several things that "could" cause the problem described. Suffice it to say that unless you have a good deal of mechanical background, you'll be lost rather quickly in this system.
Other than relying on a tech, you're probably going to be limited to finding a vacuum line off or something similar. I HAVE heard of an issue whereby a similar problem arose and was traced to a bad blend door. Unfortunately, the repair required TOTAL removal of the instrument panel (dash board). I wish I had better news for you but..........
