A/C works when it wants to

[tahoe74]

2001 Tahoe LT 5.3 2wd, front and rear a/c

I will do just about anything to resolve this problem.
When the a/c is working it works very well.

Some times while driving the a/c just stops working and the a/c light goes off on the control head. Then it may come back on or not. The only thing I have done was to unplug the a/c control head and then replug it in and it seems to work for as long as it wants to. There is no rhym-or-reason the a/c shuts off and then comes back on it just does it. I welcome any ideas and will try any suggestions.

Thanks in advance,

Try offering the ac unit a little more money than minimum wage. Your air conditioning wants to be rightly compensated for its hard work. If you don't include benefits it might just say "this job blows" and quit working permanently. Perhaps it is currently going on strike.

Control head may be failing.

do you of any way to test the ac head unit?

Swap in a known good unit is the easiest way.
