Ok The car is an LS when it was stock the ac would work fine no problems.

Now I swapped in an LSVTEC and now I am having issues with my ac. It cuts on and off at random. I could be driving and you can hear and feel it kick on and off. What do you guys think it could be? There is cold cold air coming in when it comes on.

 

Is the AC switched in te on position when it cuts in and out?
If so: Loose Belt, AC Compressor could be going bad, Electrical
If not: Electrical

 

it is suppost to do this... it is the low pressure switch. when it gets too low(this means it gets cold and the pressure decreases) it will cut off to allow it to warm up and let the pressure increase.

 

Nah it's not that. When it was stock it would never cut off. Now it cuts off like every 3 mins and comes back on. Sometimes it cuts off and on every 10 seconds. It might be the belt who knows but it's tight or at least feels tight.

 

have you checked fuses... sometimes the bridge breaks off and rattles in the plastic making retarded contacts with the prongs.

 

That would have been my first guess also. All systems leak...some more than others. I would get a gauge on it to check for sure.
