Question about Cars & Trucks
When I start the car, the fan seems to be "chugging" until the car has run for awhile. The fan will blow air through the vents than dies off but then comes back. This happens quickly to create that chugging type operation. Any ideas what that could be? Thanks for comments

it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.

The check engine light could be any number of things and the only way to find out is have the codes scanned. The brake light issue is common on E46 3 series. It is an issue were the brown ground wire that goes into the lamp housing melts at the connector causing a loose ground connection. The connector needs to be replaced and also add additional grounding wires to prevent further issues. And for fuel additives either use the cheveron techron, or the bmw fuel additive(the bmw stuff is the exact same thing, so just use which ever is cheaper).

SOURCE: 2003 bmw 325i a/c front vent
hi gc, if you are getting cold air and warm air out of different vents with the a/c on, I would recommend having the a/c freon checked. if the system is low, it can cause cold air out one side and warm air out the other. if it is low, the system should also be checked for the source of the leak.freon has oil in it that keeps the compressor internally lubricated and when freon leaks out, moisture can get in the system.

Is any air coming out at all?
If warm air is being blown out, then your refrigerant level is probably low. The car is fitted with a safety cut off, to stop the air conditioning system working if the refrigerant (R134a) level is low.
This cut off only effects the air conditioning, the blower would still function normally.

had same problem with my 01 325ci ..... talked to several bmw independent technicians and found out that the evaporation coils run across the dash from driver side to passenger side. If you get low on freon, then the driver side will continue to cool down, but the passenger side will gradually stop cooling or blow warm air. Solution ,is to check for leaks in AC and then recharge the system w/freon .... unfortunately , with my car intead of a 150.00 bill for a AC coolant recharge from normnal wear
