I have a 96 Sunfire.
In the summer my car is fine and in the winter it heats up great and blows hot air if I'm driving under 35k. As soon as I hit the highway and speed up, I lose all my heat and it only blows freezing cold air.
It has a bra but I've even tried cardboard in front of the radiator and it does nothing.
I had the head gasket replaced 3 years ago and when it started doing this I brought it back in and they replaced the thermostat. But still no heat.
Any ideas on what the problem could be? I would appreciate any suggestions, because I'm at a loss.
have the same problem?
