Chevrolet: Car Overheating After $1200 A/C Repair, start the car, electric fans

Question
Hi, My car's a/c was repair about a month ago (the entire system), now I notice my temp gage moving over to hot whenever I'm running the a/c. If the car is running but not moving (like at a red light or parked)my a/c seems like it's taking a break meaning that it is still blowing but not as cool.  Please Help Me, What could it be? The shop that fix the unit said something about a fan but at this point I don't feel that I should trust them.

Answer
Quintell,
      Depending on what kind of car you have, you probably have two electric fans on the radiator. If one or both of the fans don't run, it will have the symptoms you describe. Start by checking the fuse for the fans and see if it is blown. If the fan fuse is good, start the car and let it get to operating temp. and visually check to see if the fans are turning on. If only one is turning on, then you probably have a bad fan. You can check it by turning the car off and letting it cool and see if the fan that's not working turns freely. If it doesn't, then it needs to be replaced. The good news is, again depending on the model of car, it is usually a fairly easy do-it-yourself fix, and I could probably walk you through the steps. Check it out and let me know what you find. Good Luck!
