    Exclamation HVAC controls not working '89

    Hi, i noticed on my 89 chevy pickup that my HVAC controls only half way work. the A/C button doesnt' do anything and neither does the defrost button. It doesn't even show it on the display and nothing comes out of the vents. I checked my fuses and they are all good. so is the control unit toast? or is there something else that could be wrong? i really need this fixed before i get caught with a frosted window! thanks
    1991 s10 2.8 v6 2wd, lowered 2/2 shaved door handles, pride and joy. Now wrecked :frown: time to fix again


    Make room for my '89 silverado :smile:

    Most likely the blower relays or the fan motor itself.
    Check out AutoZone's website for information on climate control parts.

    Here is a picture of the hi/lo relay:
