No heat...

What could be the cause of low heat in the car? The temp gauge goes to about 1/4 up, is this sufficient to heat the car?

The controls inside seem to be sticking and the upper slider which controls the temp sticks in the middle range, I can move it to the far right for maximum temp but it just slides back to the center.

It appears something is not working properly with the cabling, does the dash have to be removed to access it or can you get to it from under the hood at the firewall?

Any help would be greatly appreciated, and Thanks...

I don't see that you put your car in your sig, so I don't know if you have a 78 or a 94. you could also put your name in there or we can call you SD for short

You can remove your controls from inside the car I believe.
