A/C not cold, Slip, ABS and TCS lights on

[Tman Sr.]

I have searched both recent and archived threads and found posts for A/C and slip, abs and tcs lights but not one for all of them together. I can't help thinking that the problems are connected since they all seemed to happen at the same time. A few weeks back my slip abs and tcs lights came on on at once about 5 mins from home, next time I got in my car (about an hour later) my air conditining stopped blowing cold air. A/C: I had an Infiniti dealer look at the car this week and they pruged the system, recharged it and checked for leaks non were found. System still blows warm air. Defrost mode seems to actually have a hint of cold air but not close to what it should be.The air isn't exactly as hot as the outside but again not were it should be. Its as if the system doesn't can't decide to heat or cool. Technician also noted that the condensor fan wasn't working. It will however turn on if powered directly. I have noticed that the if the car has been idling and it is very hot out the condensor fan does come on by itself.

Warning lights: The dealer scanned but "no codes present". So I just spent $370.00 at the dealer to have them tell me that they don't know what the problem is. The mechanic said that he thought the problem might be a relay or wiring corrossion issue. He said to check the area under the the battery and battery bracket for relays and wiring.Before I do this I wondered if anyone here had other suggestions. Any help would be appreciated.

Is your battery less than two years old? Up to OEM specification? Load test your alternator and inspect the drive belt and pulleys.

The battery is new, it was replaced a couple of months ago and the alternator hasn't been tested but it is new, it was replaced last year as well as all the belts.
