Question about 1990 GMC C1500
MY HEATER/ AIR CONDITONING ACTS LIKE IT IS GOING TO COME ON BUT I HEAR A CLICKING NOISE IN BEHIND MY GLOVE BOX. I HEARD THAT THERE WAS A RELAY SWITCH IN BEHIND THE GLOVE BOX. WHERE WOULD IT BE LOCATED.
Remove the glove box, you will see the relays, sounds like a bad ground.
