How do you fix a 1995 Chevy Corsica that will only blow heat out of the vent and not out of the defroster?
Most likely you have a vacume leak under the dash.Check for lines off or broken.They will harden and crack with excessive heat,such as in the engine compartment.
What is likely wrong with your 1997 Chevy s10 Blazer when all of a sudden air will only blow from the defroster at any position on the control unit?
What could be wrong if the reverse went out on my 1995 Chevy Silverado manual transmission but drive is fine?
Chevy trailblazer 2004 Why doesn't the air blow out of the front vents when the air conditioner is on?
While doing a little research on these vehicles, I ran across a reference to this issue arising as a direct result of the rear window defroster shorting out to (sorry I don't remember which) another component. I just recently read that the connector for the 3rd light will short out and blow the fuse disabling your shifting out of park. Check your fuses and the 3rd light connector. Good Luck.
Why doesn't heat nor cold air blow out of front or floor vents but does out of windshield defrost vents?
You have no tail lights or lights on your instrument panel on a 1995 Chevy Lumina but have headlights and blinkers?
2003 lancer You turn the nob for defrosting but it does not blow out of the defroster but continues to blow out from the front what do you do?
Bring the car to a machanic soon! It only takes seconds for the windows to fog up when the temp. and humidity is right and you wouldn't want to be on the highway in the fast lane when they do if your not sure of your defrost. Hopefully it's something simple...anyhow, goodluck and have a wonderful day.
