My AC on my 2013 ML350 isn't blowing consistently. I've checked fuses, replaced air filters, compressor is working, freon levels are good, blower motor works when it will turn on. I've noticed it has turned on when hitting a bump in the road. Started taking out the passenger side flooring and it turns back on. Three times now it will turn on as soon as I remove the passenger carpet so I'm thinking it may be an issue with wiring as opposed to the blower motor/resistor. Does anyone have a wiring diagram reference for which wire in the passenger floor panel/side panel could be causing the issue? Anyone have a similar experience?
