My AC compressor cycleson for 2 seconds then off for 2 seconds. I checked the pressure on the low side and it is within normal range but the air from the vents is NOT cold...cool at best. Any suggestions.

 

Iwould check the freon level, mine was doing that to, bought a can from advance for 8 bucks and she was blowing cold in no time.

 

Something's causing the compressor to cycle. Have the system recovered and recharged, or try adding a can yourself. If possible, give me a high side reading along with a low side, in PSI.

 

Had the same problem with my Ram a while back. I have a buddy that works on cooling systems for houses and cars and he told me that whenever it kicks on and off like you're describing it's almost always due to low freon, or whatever the hell they're using now.
