Not a MB, but a '91 Maxima. Sorry about that, but the info here is priceless. The HVAC controls are not working at all. I've checked the fuses and nothing is blown. I'm just curious where I should be looking to find the cause. The car has been owned since day 1 and has never had any problems, but this one looks like its electrical and I dont want to spend an arm and a leg for a station car. Pls help, its damn hot in NYC right now.
