Sounds like a vaccum line off, there should be a red vaccum line that has a rubber elbow that connects under the hood on the passenger side. You can not it see it but it connects under the cowling below the fresh air filter.
you have a fuse out...
Perhaps a stuck door in the HVAC system or a blockage in the ducts.
How do you open the stuck rear door on a 2001 Ford Escape? Try wd40 under ouside handle into openings. Opens most.
Hi, It is not the blend door, that is for heat/cold changes. The mode door could be the problem, or stuck defrost door.
the problem is when the baffles move from heat to ac and vent to defrost they either get stuck or the controllerr is bo. this system is built to fail safe in the defrost mode. Thus ac comes from Defrost vents. Apparently it is wide spred with Ford and Chev. As it is in my 2001 Ford F-350, My opinion To much Matel Toy company plastic and cheep parts we pay considerable money for from the dealers. 1) check your controller at the dash probably vacume 2) check the acutator at the butterfly flapper. Some vehicles are easier than others.....
what are you tring to fix? mitchell manuals, and aldata manuals have very good diagrams.
The air door under the Blazers dash could be stuck, or there could be a vacuum leak on the engine. The door opens and closes from vacuum, directing the air from heat to defrost.
check the alternater Something to do with your electrical in your vehical so i think you should get that checked out right away or just don't use your ac or defrost and your vehical should be ok..
The defrost fuse on the 99 Ford Taurus is located in the interior fuse box. It is in the number 26 slot.
If it's stuck in defrost your battery died and messed up the computer. Disconnect battery for 5 or more min. My 96 cooled and heated ok but was stuck in defrost
the light probably burned out
Trouble code P0751 means:Shift solenoid A performance or stuck off
