Question
We have a 93 Mercedes 300D with 250,000 miles. We live in Las Vegas. It runs like a dream, but when the temperature outside gets over 95 degrees the A/C stops getting cold, and the temperature gauge rises. What could this be?

Answer
Answer:
* Failed cooling system thermostat
* Failed A/C Temp. Switch
* Failed aux cooling fan.
* Failed fan clutch
* Failing water pump
* Plugged radiator = thermal overload
