1988 Toyota truck blower motor speeds won't work on low speeds?
The blower motor speed resister is burned out.
Why the Blower motor not work on high speed on a jimmy 97?
If the blower works on slower speeds only I would suspect the high speed blower motor relay (under the hood in the power distribution box) or the switch itself. The blower speed resistor is working if all the slower speeds work.
How to repair the high speed on my ac blower motor all other speeds work ok?
Normally when some speeds work and others don't, the problem is a bad, Blower Motor Resistor Pack. You will find it somewhere near the blower motor.
How do you find fault on heater fan not workin mk3 mondeo?
If all speeds do not work, suspect the fuse, the switch, the switch connector or the blower motor. If only high speed works, suspect the blower motor speed resistor. If low speeds work and not high, suspect the blower motor relay.
1999 caviler and the fan blower motor only has 2 speeds low speed does not work how do you determine the problem?
change the blower motor resistor . this controls the speeds . thanks paul
What causes the heater blower motor in a 2003 Trailblazer to not work in speeds 1-3 but works in speeds 4 and 5?
Probably the blower motor speed resistor is partially burned out.
What else would stop a blower motor from changing speed 1234speed dont work?
If you only have high speed I would blame the blower speed resister. If you have no speeds and the fuse is good, I would blame the blower motor or the switch.
Why doesnt the fan on your 1997 chevy s10 blazer not work when the fuse is good?
If the HVAC blower motor does not work on any speeds, I would suspect the motor or the switch is bad.
Why do speed 1 and2 fan speeds do not work and 3 and 4 do on my 95 ford windstar?
Blower Motor Resistor Pack is defective.
Why does the Blower motor only work on low speeds?
On most cars there is a high speed relay that can go bad and would need replaced .
The low speed and second speed blowers doesn't work for the blower motor?
the reason blower does not work on all speeds, is the fan blower motor resistor. The resistor is a 4-5 step series circuit, 1 resistor is added for each reduction in speed. If one burns out then so will all speeds below it. The "high" circuit usually has a separate fuse and bypasses the resistor altogether.
When the blower does not work on all speeds is it the blower motor?
usually the blower motor resistor pkg. located on or near the blower motor
