ac vacuum lines
I want to put ac in my car but my problem is when I put it on vent or ac it doesn't blow out the vent. Where do I start to look for problems. Any help greatly appreciated.

There are two small vac lines that come out of the hvac harness u need to hook one up to part vac and the other to full vac if it doesnt still come out when u have them hooked up switch them and it should work

Re: ac vacuum lines
Thanks, so I'm assuming they are on the passenger side of the car.

Re: ac vacuum lines
Yes, that helps alot, but I only see one hard line coming from the harness. I also discovered that I have a vacuum line not hooked up coming from the climate control switch, the violet color line is broke about 5 inches from the switch. I can't find where it comes from under the dash. Would this be my problem?
