The blower for heater and a/c only works on high no other speed. What could be wrong

High blower motor speed ? Your blower motor resistor is bad , high speed works off a relay . Blower Motor Problems Auto Repair Help

Its located under dash,or near glove box.

The dash panel lower side has to be out.

HEATER BLOWER MOTOR

Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.

It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

You need to replace your blower motor resistor!

check fuses, then wiggle speed control while moving, may need new dash control for lower speed, usually high speed works through relay may be the reason high speed works

most likely ur multi-switch[fan selector switch] test out put for the other speeds if no output replace switch if good test motor

There are two relays for the heater control fan,a low blower relay and a high blower relay.It sounds like the hi blower relay is bad.

Your blower resistor is bad. It controls the mutiple speeds to allow you to go from low/med/high. When it goes bad you get one speed or no speeds....It's about $20-$50 at any local auto parts store. It mounted directly to the speed switch or on the heater plenum unit on the passenger side behind the glove box....

This was wrong with my 01 Stratus and it was the blower motor. Between the part and the labor to have it fixed, it was around $130.
