Re: A.C. Intermittent

It sounds like it may need a recharge, the R134a level is low and the A/C system can't maintain the proper pressures in the system to perform proper operation.

A qualified mechanic can evacuate the system and recharge it and then perform a good system check to see if there is any leak or electronic malfunction.
