1993 Grand Prix Heater blower

First time trying this forum, anyone have info on 1993 Pontiac Grand Prix heat/air blower electrical system. The blower runs sometimes but not others, I have had it out and it runs good out, but when it goes back in it only runs some times.

Could be a few things.

When you say it doesn't run, does that mean not run at all, or only run at a certain speed?

Control panel
Resistor pack

1993 Grand Prix Heater Blower

I think I may have the same problem. The blower has just started not working. It will work at all speeds for days, then I'll stop and go in to a coffee shop, come out and the fan does not work. It does eventually start working sometimes after about half an hour or 45 minutes. I will play with all of the speeds, switching it on/off. It just started doing this and it is not fun being in Toronto in January. One other possible factor is I am losing some antifreeze (not sure how) and the 'LOW COOLANT' light comes on.

Any suggestions?
