Need some advice. My a/c switch only comes on when in number 2, 3, 4, I meant the light on the button. If I pull to one, the blower still works, but the light shuts off.

i am with you !!! mine works on 1,2,3 then on 4 the a/c light goes off like i pushed the button off , but when i click it back to 3,2,or 1 it comes back on.... so i am all ears also..... help us out !

I even replace that 25 bucks switch. Dont know if I should replace the whole unit control HVAC
