We were washing our car and my wife and kids stayed inside and we had it on. We were at a local car wash. After I had it all cleaned up when I got back in the air conditioner had stopped working. The snowflake symbol shows up on the automatic air conditioner screen but does not blow out cold air. I recently added refrigerant to my wifes santa fe and thought I would check the low pressure on my 300m. I had the car running and full cold air inside and the pressure was 100psi. I dont know how to check to see if the compressor is engaged or whatever( I keep seeing that to check if its engaged). To me it seems that its not getting pulled into the system. The air(hot tx air) blows hard but isnt that helpful. If anyone has any advice or helpful hints or things to check it would be much appreciated. Please dont just jump to some ignorant response, please be helpful. thank you
the pressure does not change with the gauge attached to it and i don’t hear anything kick in. I will check all wiring, Ive already checked fuses.
