Question about 1994 Mercedes-Benz C-Class
The A/C runs for 5 minutes then shuts off. So I turn the car off and start it up again and it runs for 5 minutes then shuts off. And over and over again.
You may be low on R134a and need a simple charge. As the Compressor cycles, the low side pressure drops and if it drops to far it will cut the compressor off till the pressure rises again. The high pressure side rises and the low side drops, but when it drops to far since there is not enough R134a in the system you get the on off cycle. The other cause to this is a bad pressure switch, or bad expansion valve, and moisture in the system as it ices up in the lines and pressure builds causing the pressure switch to cut the compressor off too. Re-cap, try recharging the a/c system for now since it's still working. Good luck and keep me posted. Be glad to help.
