HVAC Controls (1998)

Couple issues.

1) Low speed doesn't really do much. I am figuring bad relay behind the dash.

2) When I use AC the recirculation button is always lit up unless I choose "Defrost" mode. Is this normal?

If you have the hot/cold dial on max (all the way to the left) then yes the recirc light will be on.

Hah I'm such a dumbass... I thought the wording "Max" was just simply maxed out cold not like "Max"

Check the wiring connections on the hvac switch itself, the speed switch comes apart as well. check it all out and make sure its the resistor... they're a pita to change
