OK, with that info your problem is a low charge of refrigerant in the system, about 12 ounces from the sound of the frequency of he pump cycling, u have a small leak, they sell a sealer charge that works well in most systems with a small leak contact NAPA auto parts for details

The A/C pump or compressor should cycle on and off, this is normal for any car. Are you having some kind of problem with the A/C?

2007 AC does not work when vehicle is stopped when it is hot outside. Chev tech stated they all do this...Chev made a car that the AC quits when you really need it??


That is a load, are you sure this is an ASE certified AC repair mech??. Have the pressures tested to see what they are doing, you may have a slightly low refrigerant charge due to a leaking system.

Is a 1990 Chev Corsica towable behind a motorhome?


it can, but I would talk to a trailer hitch shop that installs towing kits. some of these will have a pump to circulate trans fluid to keep the trans lubricated. They could best advise you.
