If you replaced the blower motor switch resistor on a 1999 Mercury Cougar because the blower only worked on high speed and now you have no heat what could be the problem?

How do you diagnose a heater blower motor problem on a 2001 grand prix?
If the blower only works on high the blower resistor is most likely the problem and should be replaced. On rare occasions if the car has blown the resistor more than once the blower motor shouuld be replaced.
2000 Chrysler Sebring convertible fan only works on high I replaced the resistor it still only works on high if the switch is faulty would this be the cause of the problem or something else Thanks?
I had the same problem with the same year car. I've replaced the resistor several times. It works for months & then it stops working again. I think this is the 4th time I replaced the resistor, it is working okay now. I think it is a defect in with this cars fan system. I had a similar problem with my 2001 Sebring Convertible. I had the blower motor replaced, and now the fan works perfectly.
Why would a 1995 Mercury Sable heat work only on low reguardless of the setting even after the blower motor and blower motor resistor are replaced?
It could be a thermostat that is stuck open or maybe a bigger problem...like the blend door is either jammed or broken as well.
Heater fan switch not working on 1 and 2 setting on 2000 Pontiac Montana?
I just had that same problem..I took it in to have it fixed and they replaced the blower motor resistor and that seems to have fixed the problem
I keep blowing my blower motor resistor on a 99 stratus?
i think it probably because the motor has a ground problem or it has bad brushes and is is drawing to much energy for the resistor
You replaced the blower motor on 97 Mercury Tracer and it still doesn't come on What should you try next?
Was the blower motor defective, or where you just guessing. Did you apply 12 volts to the old motor to see if it was bad? Did you check the Fuse. It may be a defective blower motor resistor pack which is a common problem on this car.
What is a system too lean bank 1 on a mercury mystique?
Just had this problem. I replaced the oxygen sensor and it appears to be running fine.
Replaced battery and alternator on 97 mercury sable and it keeps stalling what is the problem?
Idle air control? Fuel pump? Coil?
Fan Doesn't work for your 1988 Mercedes 300E?
change the resistor if the problem continues try the fan with cables directly to battery and you will see for sure that the fan need to be replaced.
I have replaced the blower motor resistor and It blows on 1 and then it stops blowing completely what is the problem here?
Have you checked to see if your 12V dc relay under the hook is working properly?
Why do resistors burn out?
Most often a resistor fails because it is unable to properly dissipate the heat generated by the current flow. A resistor rated for more power (higher wattage) may resolve the problem.
What cause 1999 Mercury Cougar blower to not work on low?
More than likely the culprit is a defective blower motor resistor pack. It can be the switch itself, but it is unlikely. I replaced the switch and had the same problem, its most likely the resister, this is a recall so your local ford dealer should fix it for free if not id call up ford and complain
