We need a DIY A/C install! AC

[xintersecty]

Did you check the wiring diagram and see that the compressor signal is triggered by the computer? If so maybe all the inputs are not right for the computer such as the low/high pressure switches and temp sensor.

A friend of mine,the guy with the tech2 scanner checked it and said the relay is not being energized.Looking at the wiring diagram he said the computer has to energize the relay.I took it to the dealer to see if the computer has to be updated.They didn't have any luck and it was getting late so I have to take it back next week.I'll have to find a wiring diagram because I'm not sure if its the ecm or the bcm that has to be updated.I'm not having any luck finding someone that has done this install.I would like to know how they got it to work.
Thanks for your input.

Is this not the step by step to turn it on with a tech 2? (on page 3 of this thread)

Everything is installed and charged.The a/c has been turned on with the tech2.It just doesn't work.It appears the relay has to be energized by the computer and it's not.

Have you really investigated the inputs like I suggested above? A computer can only do what it is told and the inputs are part of that process.

Such as signal on, low pressure switch, high pressure switch, t-stat.

I checked the pressure switch and there is no power going to it.I don't know what else it could be.It's going back to the dealer on Monday.They weren't much help the first time it was there.I'll see if have more to offer this time.

Do you have a wiring schematic? What year is your car.

Now the dealer had to call GM in Europe to help with this problem.So now they're waiting for a call back.They said it could be 2 days or 2 weeks they have no idea when they'll call back.

I thought about a ghetto ac portable in trunk with electric from alternator and something to convert the voltage higher. Lol mcgiver
