I just noticed that my front heat is stuck on floor/defrost. I change it to dash vent, and very little comes out and most of the air is coming out of the floor/defrost. Vacuum line?? Door flapper stuck?? Switch??

Where should I start looking? Not sure where the door flapper would even be located at and even how to get to it. Can I test my switch selector?

Thanks in advance for your help!!

 

Check the vacuum lines to the front hubs on both sides......they follow the brake lines

 

Do your other blend doors (temperature; rear system) work in the system? If it's just the one that died, it'll probably be just that door. If it's all the doors, then it's probably vacuum.

I seem to remember reading something about when vacuum is lost it goes to defrost, but I thought it was full defrost, not floor & defrost. I've not dug into this system yet fortunately, I just remember reading that before I did the front hub job.

 

Yes, the temp adjust works, I believe the rear works as well, but I need to go out and verify.

Any idea where and how to find that blend door??

 

To the top!!

Anyone know where to find the blend door? Instructions on how to get to it? Everything else works, its just stuck on floor/defrost.
Need to get this fixed and its not in the budget to take it in to the shop
