Question about 1997 Chevrolet Blazer

1 Answer

I have a 91 chevy s10 blazer and the heater/ac does not turn on at all, checked all fuses and changed blower motor....................NOTHING. My frustration level is mounting-help me please.

Blower motor resistor?? Is there anyway to test more stuff before I put more money in for things I don't need or are not broken.

Trace the voltage. Is there voltage at the motor? If not trace it back through the resistor to the switch to the fuse. That will probably tell you what you need to know. Does it work on ANY blower speed setting? Replacing parts before testing is ALWAYS going to be frustrating.

SOURCE: 2005 Chevy astro van, 4.3L A/c, Blower motor,

It could be a bad blower motor - tap on the blower motor with the end of a hammer when you have the switch in the on position - if it comes on then it is a bad blower motor. If it doesn't come on I would check to make sure you are getting power and ground to the HVAC control head.

I have a 2002 chevy s10 blazer when i turn on the heater the lights on the dash will come on like when you are starting the truck and the blower don`t work


Note the diagram for blower motor. Note the fuses, not only check the fuses, check the fuse circuit for voltage, use a test lite. Some of those fuses get ignition feed, they go hot with the key on.
You may have to check feed to and from ignition switch when problem is ongoing? Could be problem with ignition switch? Don't replace anything unless your testing points in that direction.
At the blower motor wire connector, purple wire is voltage, black is ground.

How do I replace the blower switch in the dash without breaking up the dash


Are you sure that you need a blower switch? There are other items that are prone to going out before the switch like the resistor or the motor, but if it is the switch you first remove the large piece of trim that surrounds the radio, heater controls, and instrument cluster. This will reveal the screws that hold the heater control head into the dash.
