1991 Ford Tempo Blower Issue

Home  \  Repairs & Maintenance  \  1991 Ford Tempo Blower Issue

Hey Guy's,
We'll I'm from NY. I've used this before but forgot my old username,lol. Anyway, The past week or so I noticed a problem with my tempo. It blows hot air from the floor vents with nothing turned on, and if I flip it to cold it blows out cold air. Now if i press any controls for the heating and cooling it does nothing but blow air hot or cold out (depending on which it is set to) of the desfroster vents. Like let's say I press panel vents and but the blower on high all it does is blow the air out to the windshield defroster or let's say I push floor. The same thing happens. Any idea what is wrong with my :cussing: car?? ,lol

You could have a few things happening...however, from the information given:

1) The blower itself is working just fine
2) The heat control valve / heater core is working properly

Since you push buttons to change the vent modes, you probably have an electric (motorized) climate control, which will make it more difficult to fix.

By the way, i'm speaking from experience on a Toyota and a Honda, which may not be exactly the same. However, the systems I have worked on have a large "disc" that rotates and directs the air to different tubes which eventually exit th e dash as vents. Pushing the buttons to change where the air flows out of would send a signal to a motor that turns this "disc". The "disc" may be stuck, the motor to rotate the "disc" may be broken, or the control unit that sends a signal to the motor may be faulty.

Yeah, that was what I was thinking. I recently replaced the bottom light that was burnt out for the push button controls and maybe i knocked something loose. But I'm gonna go and check into it. But like you said and I agree it can't be 1 or 2. I'll let you know how I make out :smoke: Dan

However i can still regulate that air for hot or cold. So yeah go figure right :ticking:
