Daughter typing, shes faster than me. I have decided to open a different topic about the HVACs used on the VE's. Now I bought a replacement HVAC module for my cheap VE and the one I got is for an omega, anniversary or any other single zone HVAC system. Unfortunately I did not record the part numbers off the original HVAC on the car now. The one that forgets to turn on the front face vents every now and then. Yes I shouldve taken part numbers when I had the glove box out but when the ebay replacement arrived I removed the existing HVAC unit out today and found that both were completely different in their numbers. I dont know which one is the part number. Now I still tried it and it worked perfect for the first 20 minutes. Everything was accounted for. All vents worked perfectly. Everything was 100% but one time it forgot to start the air con on my face or ignition on it was on my face but as soon as you start the car it disappeared. Now it only did this once and after this it was okay. I cannot test it all the time like this, stop and start, stop and start. The car and the air con just for testing purposes only otherwise I might end up damaging something else. I will give you the figures of both HVAC control modules and possibly someone might know why they are different considering it should come from the same car.

They must mean something e.g. SW = 15, HW = 9, CI OR CL = 05 for the ebay one of course its different on the genuine unit. So the million dollar question is, what does these specs mean?
