God knows I love my little car, but I hate the Climate control. 1998 C230. I leave the control on 72 degrees which is the factory preset, when starting at any time in the garage the system works great. However if the car is left out in the sun & the interior is very hot the a/c comes on normally for a couple of minutes (sometimes one or two minutes, sometimes ten) then quits, the blower then proceeds to gradually increase to max (blowing warm air!). If I pull over, switch off the car for 30 seconds & re start it the a/c will come back on again for a few minutes. More often than not after doing this two or three times it will stay on, when it does work it works normally! I also notice that when I switch the car off to reset the a/c after a few seconds there is a fairly loud click from behind the center console in the area of the controller, sounds like a circuit breaker re setting, six months ago had the blower regulator replaced & the a/c serviced & charged at the dealership, I am still walking with a limp! I would very much appreciate any input, thanks Phil
