Climate control help

[Mike Kopstain]

I'm going to be working on someone's SHO tomorrow. Here is their problem, the air only blows out the defroster vent, no matter what position is selected. I'm thinking that it's either a vacuum leak or a faulty EATC unit. Any thoughts?

Sounds like a vacuum leak to me. The '95 shop manual shows that, in the absence of vacuum, air will be delivered to the defroster outlets only. Check the coloured mini vacuum lines behind the glove box. I have recently had a problem with the recirculation door not operating correctly and it turned out that its white vacuum line was not connected properly.

Found it! Broken vacuum line under the hood.

this is the problem I have. The air is only delivered to the windsield defroster vents no matter what position it is in. What is the deal? I really need help, it is COLD in Michigan right about now

if this is the same as the problem u encountered, where is the vacuum lines under the hood?

I had the same problem with my 92 you can check the Vacuum actuator. Open the glove box and pul it out of the holders. Now you can look up in the dash to the left and see the top of the motor you can push it down i Believe if it stays there you probably have vacuum running to it and the motor is bad... However, you have to take the vacuum line off to check them... You must do this from the bottom side of the dash its one of those you can get to all parts you just have to come from 3 diff. angles... Anyway pull the line off hit the button to make it work and see if there is suction... if there is then the motor is bad...
