Customer Question

I have 2006 Escalade with duel AC. Just a little bit over a year ago I had remote control start and a better alarm system installed. Just recently in the last few months I can be driving down the street and the AC will cut out and maybe a few minutes later it comes back on. This could happen 1 time or numerous times. I would take it back to the place that installed the equipment to see if something was wrong. One time they told the ground wire was loose or something to that affect etc. Last Friday I pulled out of my driveway only to have the AC go off, and along with that the battery light, ABS light and the gas gage. The drivers side window worked but nothing else on the door worked. I again took it back and had them take it off because we didn't know what was causing the problem. The equipment or my vehicle itself. Today the ac went off and on again just like before but the gages were fine. Everything was good after they removed the equipment until today. My husband told a little while ago that when they removed the equipment they just snipped the wires in the fuse box instead of removing them completely. Can you shed some light on what might be causing this.

Expert:  Chris (aka- Moose) replied 2 months ago.

When the front AC stops is the cold air stopping or all of teh air flow or is the screen on the HVAC going blank?

Thanks, ***** ***** the AC circuit if needed.

To figure this out you need to start figuring what is working and not to blame to have a direction to see what is possible to blame. Step on will be removing the AC relay when the AC is commanded on but not working. You should see 2 power pins and one ground signal pin. Most likely this ground signal is the issue. It comes from the PCM. If that is the case then the HVAC control or the PCM will have codes stored telling you if there is a pressure sensor reading issue causing this. Can you do these tests?

If you're confused on what to do now or later. You have already been charged the full question value. It's now time to compensate the tech that helped you.
