Heater problem
1998 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic

Blower motor fan worked only on highest (5) speed. I changed the resistor and that fixed the problem for a few days but it again now only works on highest setting. What's my next move? Thanks!

I'd check the lower speed feed to the resistor assembly. For the lower speeds, the wire colors are yellow--tan--lite blue--purple, depending on the lower speed setting, one of those wires should be hot, with the key on and the blower on. The yellow wire is the feed for the lowest speed. There is also an hvac fuse 20amp, that protects the lower speed circuits.
