I had the same problem - it's a bad resistor. Most mecahnics can change this and it didn't cost a lot if I remember.
Could also be a short to ground. If it runs all the time that's what it probably is. Get a wiring diagram and figure it out
The blower motor resistor pack is defective. Replace it.
Replace heater motor resistor.
Why does your 2001 Nissan Pathfinder heater fan stay on high even after I try to shut it off?"
your tranmission is shot.
Maybe because your climate control system needs to be repaired....
12 volts on the low end, 18 volts on the high end.
If the engine is at the proper temperature and the coolant is full, you have a restricted heater core.
It is the resistor, replace it.
the best tires i have found that fit beautifully and provide the best handling are 275/60/15, go with hankook or cooper gt, they have a high rating and are well worth it once you get on the road
its probobaly broken get it a service
try replaceing the switch that controls the low to high for heater It's gonna be the blower motor resistor (near the blower motor).
Bad resistor pack on blower motor? Bad switch?
Trouble code P0599 means: Thermostat Heater Control Circuit High
Most likely a failed blower resistor.
Check the low speed relay and the resistor at the motor
bearing is out,replace motor.
Trouble code P0499 means: Evaporative Emission System Vent Control Circuit High
Trouble code P0546 means:Exhaust gas temperature sensor circuit high (bank 1)
Dakota High School was created in 1995.
If it has only high speed, the blower motor resistor has to be replaced to get all speeds back.
the blower motor reducer in the box under the dash on the passenger side its a little white ceramic lookin thing. someone told me they go bad when the blower motor is going bad
I just need the location of the heater & blower unit of the 2001 Nissan Xtera. E-mail email@example.com thank you
A high-pitched whine in a Dodge Dakota only when the weather is cold might be a normal thing. When the weather gets cold, the belts, starter and alternator need time to warm up. Try a little drop of dish soap on the fan belt to see if this helps quiet the whining.
on the right rear of the engine kind of high.
