Hey guys, my a/c has been blowing hot lately SO, i went to the store and got an ac recharging kit... i followed all the instructions and connected it to the low side system with the car on and the ac turned all the way up. When i pressed the button, the refridgerant just "backfired" and started coming back out of the nozzle button.. why is it doing this??

 

have you checked the pressure?

 

NO i havent...how do i do that??? Thanx
