When A/c was first turned on the fan would turn on f9r long periods of time my a134 was super l9w atbthat point so.i started to.fill it and right before i filled it to.the correct amount the fan turned off and would turn on evry 3 to 4 minutes and only stay on for.1 to.3 seconds at the verry most.and now my A/C blows wormer.than it did before i filled up the coolant in it.

 

would def take it to a shop that can evacuate the a/c completely and refill it. the valves are known to leak. mine did that when i was low on freon, took it to the shop for a proper evac and refill. thankfully didn't have to replace the valve yet.
