It is under the dash on the right side where the center console connects to the dash. more commonly known as the "final stage unit". These are very common to go out. They are very inexpensive on ebay or amazon and there are lots of walk through tutorials on youtube. You will not be able to see the aluminum pins because they insert into the air duct.

If you do not run even one level of performance as the needed engine control unit, check fuses! If they are okay, the fan is defective! is a frequent defect no only X5 E53 series

Where is fuel pump relay location 2003 BMW 745 SERIES LI


Hi Greg-
The fuel pump is provided power by the SBSR- right side B-pillar airbag module. You can check for power and ground at the connector of the fuel pump across the 2 larger wires. The brown wire is ground. You should have battery voltage to the connector.

WHERE DO I LOCATE THE FUSEBOX THAT HAS THE AC BLOWER FUSE


Its probably not the fuse, but instead the blower resistor located under the dash. They are usually accessed from the glovebox side of console up near the firewall. This truck should have 3 fuse boxes, one back by the battery, one in glovebox (drop-down panel), and one under cabin air filter under hood. All should have fuse diagrams with them and there should be one in your owner's manual.

Hope this helps,

Where is the blower motor resistor on a 2003 impala


If it's a manual AC/HEATER SYSTEM It's in the blower case assembly,(to leep the resistor coils cool when running) It has 2 screws holding it in place and a connector with 4 or 5 wires in it. If it is a EATC Unit, (Electronic Air Temprature Control) it uses a electronic transistor control located under the glove box left side under dash.

My ac is blowing at various strengths no matter what setting


the final stage transistor(blower resistor) has failed most likely. It controls blower speed from a signal from the ihka (a/c control panel). the final stage receives the signal from the ihka of drivers preference blower speed. the final stage pwm (pulse width modulates) the blower motor. which means it turns it off and on very quickly to speed up or slow down the blower motor speed. It isn't the easiest part to replace. Usually at a dealership i would expect to pay somewhere around $600 (including diagnosis)but don't hold me to it. bmw dealerships stand behind their repairs and usually include a warranty with the part of 2 years unlimited mileage.
