S550 hvac issues.... Not resistor i think 955d error
Hi al i have a 2008 s550. Not seeing anything much on this code 955d lin bus error... The fan turns on and off intermittently, changed blower, resister, checked ac module, all looks good. Im looking for any other advice. Attatched are screen shots from the Lin bus... Any thing will, advice, wiring diagrams....
Thanks all.
The fan alternates between off and emergency, when hvac set to off. When on auto emergency stays on the fan cycles on and off and the call speed flashes 88.4 intermittently
