This is on page 103 of the 2007 owners manual. Maximum cooling. At outside temperatures above 32 degrees F/0 degrees C and when the engine is. running, you obtain a maximum cooling effect as soon as possible. The automatic climate control switches to the lowest temperature and operates in recirculated-air mode.Temperature control is by left and right hot engine coolant radiators, after the one AC evaporator, each with its outlet thermometer (that you can see just inside the left and right center grilles). MAX shuts all the flappers except those that blow in your face, sets blower speed to maximum, and thermostat to 60°F. 1. I set the auto settings to max power (of the three levels provided) 2. I have turned off the rear vent (since nobody usually is in my backseat) to get more power in front vents. 3. I brought the car in to dealer and they tested the a/c levels and said its working fine. I have a 1999 BMW 323i which the ac was working perfectly fine. My instrument panel for the ac/heater blipped and went black, which shut down my ac. Now nothing turns on, defroster, ac, heater, fan speed, temperature control; nothing lights up. I checked the fuses and they are all fine.

2When the ignition is on, set the heater to the highest temp (84 deg.) and set the fan on low. 3.Hold down the accelerator pedal for 10 seconds then release. This activates the water pump and it will cycle for about 12 minutes to vent all the trapped air into the coolant reservoir (it sounds like a min washing machine).
If no codes are being thrown use Chevron Techron fuel injector cleaner (concentrate). It solves rpm fluctuating upon cold start-up. Also, for most BMW problems start off by scanning your car with the Peake Research Tool. It contains the actual BMW codes. 2006 330i [0.00] Rear Defroster Stopped Working. Hi Guys, This morning I had started my car and my front defroster worked great, but my rear defroster didn't do shit. This is the first time this has happened. I have searched online, and most people say to check the fuse, so I will do that soon, but was curious if anyone has any other BMW's map is ridiculously stupid, so it's a bit tough to be sure you have the right ones and all of them. 121, 177, 181 seem to be the right fuses, but who knows which fan that might be for. 2001 330xi strange issue with radiator fan. The engine heats up to a temperature of 93 degrees (water in the engine block), then the fan is started, which works at constantly higher revs and maintains the temperature in the range of 90-93 degrees, turns off only after turning off the engine, after starting it again after reaching 93 degrees start up again Easiest thing to check is fuse first. Then the final stage resistor and the blower motor. There was a service bulletin out for the blower motor burning out due to leaking cowl cover but unless you have water on your pass side floor then I would rule out the leak.just out of curiosity, where is the heater control valve located on the 2006 e90 bmw 325i? i took off the cabin filter and frame but I could not find it. if this vehicle has a heater control valve, they do a good job of hiding it.
