My AC works fine but after car gets hot = (over 100 to 110 on the MBZ "Celcius" temp gauge on the dash)I turn the car off and when I restart it blows hot air. Once the car sits for a few hours it runs cold again..New thermostat,
I have new cooolant,rebuilt radiator, new Freon, and all lines have been tested and there are no red dye leaks..
Is there a temp. heater valve, a thermostat in the AC unit somewhere...two shops have been unable to resolve one is a MBZ dealer!!! HELP!!! I spent over $1500.00 and it is still not fixed!!! I live in Vegas and need AC bad!!
