Just bought a 95 v6 manual:
The heater/Airconditioning only blows through the defrost
The windshield wipers stay on constantly

Tried a new wiper/turnsignal switch= same thing
Tried a new HVAC panel = same thing

I'm thinkin the AC thing is vacuum related but not sure where to start or how to check

I had the air blowing through the defrost problem with my 94 gt. It turned out to be a vacuum leak check all your hoses and vacuum valve.

i think i have that problem in my 96gt. all the sudden im not getting the upper vents to work. only the defrost and the floor ones. also, why did you post this in 4.6l tech? lol

The most commom cause of this is the hose that goes though the firewall. The flapper that directs air is vavume controlled. Check right at the firewall.
On the wipers you have a Wiper Control Module. Thiscontrols the wipers.

As stated, vacume leak, and wiper module/motor.

I always say, $75 ftw, dealer diagnose, no throwing electrical parts.

Fords are tricky with electrical, if you are not experienced with a DVOM.


I recall a AC Module from hell in a Ford Taurus, only to find it was getting 12-14 volts, but not enough AMPS. Wiring harness FTW ON THAT ONE.[:'(]
