My blower motor works at high speed only...replaced resistor with no success...fan will work normally, then go back to working on high only...A/C will work fine one minute then the compressor will turn very slow and put out no cold air....seems like when the blower quits working the compressor begins to act up...HELP!

 

humm they should not be related in that way. U have a bad blower motor locking up and nuking the resistor. the compressor moving slow u should have a nise little belt noise if thats the case. if yes new compressor time.
