all is has is the plug with the 4 vaccum lines that plugs in the selector control thang under the radio
not that i know of , i just unplugged them on the thang under the radio ...... but plus , as i said i took the blend door completly out of the truck and the heat still doesnt get warm
Its been about 6 yrs since I had one apart...so yeah I would have to get my hands on it but I bet I can fix it
