Hvac blower motor won't turn on, no matter what speed setting it is placed on.
1993 chevy s-10 2wd truck, no heat nor a/c, compressor does not run regardless of switch position.
Blower will turn off after 3rd blower speed, what is wrong and how do I fix this problem?
blower motor does not turn on
a/c and heater blower wont work
Just the highes speed don't work. The other 2 does fine.
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.
Lost 2nd speed.
Live with it. 1,3, and 4 speed are sufficient.
