My heater blower is only working on high how do you determine if it is a resistor or not 94 Grand Marquis?
I had a 1995 do the same thing. Do you have the Automatic Climate Control? If you do, the problem is the control unit itself and ir runs about $400-$500 new, but you can usually find one in a Junk Yard for around $100. That's what I did and it fixed mine. A mechanic told me that there is a part inside of the control unit that goes bad. The control until is in the dash. It's extremely easy to change out. I did it myself. Hope this helps. Josh
