My 97 buick lesabre limited heater/ac blower quit, it has the climate control,I checked all fuses.

My Lesabre did that and I am not sure how my mechanic did it but he said it would cost an arm and leg to repair it so he hooked up a separate switch under the dash and everything worked after that. a seventy five dollar fix is better than three hundred. See if your mechanic has an idea. He said the off and on part of the automatic switch was not working but after he put an off and on switch in the line the climate control worked.

What have you checked so far ?
Could be the blower motor, the resistor, a fuse, bad ground connection, or the HVAC controller if you have climate control.

If you mean the blower motor stopped - check for voltage at the fuse and the blower relay.

check blower relay located under hood or passenger side kick panel also climate control panel is common problem on these and other GM cars

You probably have a bad blower resistor

disconect the negative battery cable from battery for 20 seconds and replace cable back,then try ac let me know if this helps u

check the fuse box and under hood ,check one by one with the climate control on and radio lights on , and you will see when the radio its off or on.

the fuse is in panel with other fuses,however it will say a\c instead of heater. You may want to use a test light to check for voltage at the blower motor plug. To see if current is going to the fuse. Check the other fuses too. since they are linked in parallel to the the acc auto climate .

EVAPORATOR CASE, UNDR RIGHT SIDE OF DASH, GEN RESIS. IS VIISBLE. IF YOU CAN USUALLY SEE WIRES, FOLLOW

that would be a good suggestion. the guy probably do not know what he is talking about.

on another thought, from where you buy them, dont they have a way to test what you are buying if it is good or bad?

original problem : no power going to the compressor.

solution: test first if there is refrigerant. there is a pressure switch in the system that would prevent the compressor form engaging.
there is a fuse that would break in case you have a faulty coil.
there is an ac relay that could break anytime.
and so many more......

the last thing to replace is the climate control....

tnx 4 using fixya,
