Loss of One or More HVAC Blower Motor Speeds on Chevrolet S10

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

Blower will turn off after 3rd blower speed, what is wrong and how do I fix this problem?
This has happened to me as well. The fix is a simple $18-$25 part, the Resistor Block, which is located inside the back Firewall adjacent to the Blower Motor Housing. Two (2) screws and it pops right out. Easy to replace. This will usually go before the switch which is much more difficult to access inside the dasshboard.
