i am going to put in new transistor's in each housing, but I need to know which one is which and the correct part #'s for both. In photo 1 and 2 is the transistor for the evaporator housing and photo 3 and 4 is the transistor for the heater core housing. as you can see in the evaporator housing the transistor must have got hot and the nuts on the end of the screws that hold the transistor in place melted thru the plastic. Which probably means it is bad. They both look about the same but idk ? and the 5th photo I believe is the temp sensor? any help will be appreciated.

The attached will assist you with replacing the transistor. Your's has been replaced before as it's attached with nut/bolt, rivets were used originally. The transistor part numbers have changed to currently available, I'll try to locate them they're filed under something on my computer.
