Did you check with OBD ?
Maybe the problem with AC clutch relay.
I have same problem with my 1993 Grand Cherokee Limited, and I bring to my mechanic and fix, because the connection on AC clutch relay relist.
Hope can help
the resistor for the blower motor is busted blower works on high with out it
Check your servos.
I have been told that when the fan blower only works in the last setting, it is usually the result of a bad fan resistor. I ran across this question trying to find where the location of that resistor is. The Haynes Repair Manual for the Dodge Spirit does not show the location...
Bad blower resistor?
The wiring, switch or blower has failed.
when a blower motor only works on high, it is usually due to faulty resistor board. Should be located in the duct near the blower. the purpose of this is so the air blown by the blower keeps the resistors cool.
The blower motor works on only one speed. The blower motor resitor pack is defective and needs to be replaced. It is located on the blower housing in the engine compartment just below the blower motor.
The Blower Motor Resisotr Pack is defective. Replace it. diagnose the blower motor resistor circuit... read up on how... everyone should have a manual for their vehicle, and a professional shop manual should be available at the library in the reference section for FREE...make copies of the right pages and fix your vehicle like a PRO! :) good luck Dave :)
The blower may simply have burned out. If the blower is out then the heater probably still works.
replace the blower motor switch
could be a fuse, a relay, the blower motor or the blower resistor. It's easy to check the fuse, using the owners manual. I am not sure where the relay is, and it requires special tools or replacement with a known good relay to test. If the blower works on high and no other speed, then the resistor is bad. If fuse and relay are good, and blower does not work in any position, suspect the blower motor itself.
manual works manually and automated works automatically
The blower resistor has failed.The blower resistor has failed.
Check for a bad blower resistor at blower motor
Defective blower motor resistor pack.
bad blower motor
Should under dash on firwall near blower motor.
If you are saying that the blower motor only works on the high speed setting, then the Blower Motor Resistor is defective and needs replacing.
The front blower should have a resister to change the speeds. It is usually mounted close to or on the back of the blower motor.
blower resistor is bad
Defective Blower Motor Resistor Pack.
Loose connection or blower motor is bad
You need to replace blower motor resistor.
bad blower,buy a good one and replace
check the blower motor resistor
