I don't have the car in the USA it's in Costa Rica and I recently in January had a ac compresor installed
Expert:  tims auto repair replied 9 months ago.

ok..from the way you explain,,you either have too much or not enogh r134a gas in the system

Expert:  tims auto repair replied 9 months ago.

i would think that sense you did have the compressor replaced,,and it did work,,i would think it is likely low

Expert:  tims auto repair replied 9 months ago.

but,you will need to have a gauge to test the pressure to be sure

Expert:  tims auto repair replied 9 months ago.

you can buy a recharge kit at your local parts store that will have a small gauge that will work for you

thanks

The shop where I had the compressor replaced tested for amount of freon and it was full could it be the amplifier
Expert:  tims auto repair replied 9 months ago.

it would seem it is freezing up[from the way you explain] from too much or too little feon]

Expert:  tims auto repair replied 9 months ago.

it is possible that you may have a bad pressure switch,,but be sure of the freon before doing anything

thanks
