I have a '95 C220 with 115,000 miles. The aux fans never come on. When stuck in traffic the AC is not effective and if the outside temperature is over 95*F, I have to turn on the heater to keep the temperature at 90*C to 100*C. When the outside temperature is 90*F or cooler the AC works very well and the engine temperature fluctuates between 80*C and 90*C. I could not find the fuses for the aux fans.
Any input appreciated.
