Codes??

[montecarlo79]

Went to the dealership, to get my car fixed after the water damage. The parts they replaced fixed everything. They gave me a bill that has all the stuff they did to it and at the bottom it sad this about the codes:

Check SIR SYSTEM and found numerous codes in the DERM. The DERM has a codes for an internal fault and needs replaced before any other problems with the SIR can be checked or repaired. Replaced DERM and retested found no other codes. Codes are 71 current. History 23 26 33 34 35 41 42 61. 42

I was wonderning if anybody could tell me what each code meant? Thank you ind advance.

I'd just stick to that code 71. The others are old, I don't know if they were pulled before or after they did the work, but I would think it was before.

Code 71- A/C evaporator temperature sensor. Low temperature indicated. Check pressure sensor and/or A/C clutch for possible short to ground or open circuit in sensor wiring. Replace sensor after verifying wiring and connections are okay.

My haynes book says nothing about this damn sensor? were the hell is it? more importanly is that what is causing my a/c to not work?
