Question about 1996 Chevrolet K1500
I was told it is the heater relay switch that is making it only work on high...correct? But why is it so noisy on high? Is there something else wrong or is the relay switch not the problem?
Hi. If you haven't figured this out yet, the issue with the blower only working on high is caused by a faulty blower resistor module. You can get these from the dealer or NAPA. The issue with the loud noise is most likely caused by either bad bearings in the blower motor or the impeller (fan blade) on the motor. The resistor module will probably run you $40.00. The motor assembly, about $150.00.

Sounds like relay to me but what blew it, most likely dry bearings on blower motor causing your noise clean oil fan motor install relay
