Pontiac Grand Am Heating/Cooling
The fan won't work when it is on setting 1 or 2 but when it gets turned up to 3 it blows to hard. I am wondering if it is something that can be fixed easy I would like heat and air but not on high.

On my car it's easily visible, but I was wondering if someone here might tell me where to look. Do I have to get under the car?
I know this is not a complex issue because i've done it on my own car, it's just that I'm not familiar with the Grand Am.
Thanks
I've had the same problem with the resistor board. I also cannot get the rear screw out! How did you accomplish this? It seems to be an odd size too, do you happen to remember the size?

The radiator fan should run when the engine temp reaches about 195F (if I remember right for a 95), or full time when the A/C is on. If that's your problem then yes it will overheat especially when running and sitting still, maybe OK when your moving but depends on conditions.
If your talking about the heater, then provide more info.
thanks
I've owned three GA's and have had to replace that knob on all of them at one point or another.
If it's not that and it is the mode control switch itself, then the entire assembly (fan speed, temp, mode control) has to be replaced since it's supplied as a unit.
I'm willing to bet though it's just a cracked knob.
Are you sure that the knob you put on isn't also damaged? If you can hear the hiss all the time, regardless of the setting, then it's probably leaking vacuum. This can also happen if it's between positions since it vents vacuum under certain settings, that's why I say to be sure that the knob, even if it's a different one, isn't also damaged. You may want take the knob off and try using a pair of pliers (carefully) to turn the shaft to test it and make sure.

If you brought this to any trustable garage and they "Cleaned out the sludge" then they didn't know what they were doing. If there is slug in the Engine more often then not, if cleaned out will pose more problems then if left in. This is what my Mechanic told me and I did some research and found out to be mostly true. There are times where they can clean this out but they have to also do other replacements of certain parts as well. Hope this helps!
Thanks!
