Air conditioner doesn't run when I use the remote start

SOURCE: We bought the 2004 envoy

lots of cars need the gas in the air conditioning units to be recharged avery few years. this is a relatively common fault and can be remedied quite easily. either yourself with a top up can of refrigerant from an auto factors, or by an air conditioning specialist. i would recommend the specialist myself, as they are usually quite reasonably priced, and can check the system for leaks, and any other faults at the same time.

Not sure what you mean when you say an air conditioner problem like if the compressor clutch isn't engaging or the blower motor isn't working, that kind of thing. Anyhow, I am about 99 percent sure they are not in any case. What I did do for you is give you pictures of the fuse layouts as well as the descriptions for each fuse (see below). You mentioned that you didn't have an owners manual. If you would like a copy, email me at [email protected] with your make, model and year and I will be happy to email you a copy. Don't worry, there is no cost for it. I hope this helps and good luck.

SOURCE: Changed alternator, now having problems

You may have disturbed, disconnected, or broke a vacuum line or fitting, or forgot to reconnect it when you changed the alternator. A vacuum leak will certainly cause both of the problems you describe.

It sounds like vacuum is not getting to the vent, heat and A/C controls. Find the vacuum can. It may be under the hood on one of the inner fenders. The "one-way" check valve is usually located in the line and close to the can, make sure it works properly. The valve could be the very thing that's causing the problem. Trace the lines back to the vacuum block at the intake manifold or fire-wall, and also back to where the line goes thru the fire-wall. Check the can for leaks or obvious holes. They used to be just a plain metal can, but it could be a plastic ball. Check the lines as you go, for breaks and rub-thru's. Move the controls thru all settings and listen for vent door movement. Worst case is a bad vacuum motor or air flow position selector switch. If you have been driving around with the Temperature knob or control set at the same spot for months, move it from fully cold to fully hot several times and wait for the air temperature to change each time. This will help reset the blend door and vacuum control system. Hope this helps... Let me know what you find.
