The heater blows only on low. Is this the blower motor resistor?

When the resistor fails, you normally lose all speeds except the highest speed. I would get this checked to see why you only have the lowest speed, it may be the switch.
What happens when you select a higher speed, does it continue to blow at a slow speed or does it stop working?

Hi, This isn't consistent with a bad resistor, but that doesn't mean it can't be the resistor. Since the symptoms are so odd, I would suggest you get this diagnosed. Let us know what you end up finding out!

I would check the A/C control before replacing any parts have it diagnose at a shop so you don't waste your money.

bretb: It stays at about the same speed.

There are 4 positions on the dial...let's say 1, 2, 3, and 4. Positions 1, 2 and 4 seem to blow at what should be 1 and position 3 blows at what should be 3 or maybe a bit lower.

did you ever fix your problem with the blower? mine blows on 1 and 2, but blows like 2 when on 3, and like 1 when on 4! could you please send any response to firstname.lastname@example.org ? thanks!

actually no. however the other day it worked on high for about a day then went back. mine blows at the same speed whether it is on 1 or 4.
