1993 SL500 A/C fan speed
My daughter's SL500's A/C fan won't stat running at high speed (#4). After maybe 2 or 3 minutes, it turns itself down to #3 speed but the display still indicates that it is on #4. I replaced the evap temp sensor and made no difference. Last month I had the compressor, dryer and expansion valve replaced and according to my friend who did the evac and recharge, all the pressures were great. Anyone have any ideas on this?

FYI to all: dirty cabin filter overheats the fan controller so it turns it'self down so it doesn't cook. Thanks for everyone looking over my question though. cheers.
