hey guys. this problem has me stumped.
fan option buttons and AC don’t work/ engage…?
the fan blower works. but i can’t change the fan options. "feet, windshield"etc.
heater works tho. but the AC light but never turns on when pushed in and AC doesn’t work.
91 LS, stock.
-checked all fuses. in car and under hood.
help please.
one is the mots common issue ever, your blower motor resistor, search and youll find step-by-step how to replace it.
the AC not working is a different animal though and im no AC expert. mine got yanked the first week i owned the car. if it ends up being a part you need that broke let me know, the whole system is sitting on the floor of my garage.
good luck, wish i could help.
misread the initial problem.
COOL. THANKS … wEASEL , I’ll look into that blower motor resistor.
