CHECK FOR VACUMN OR SWITCH

Tom is right , only one relay for the fuel pump . What's up with the air pump ? Your vehicle doesn't have an air pump , that's why fuse doesn't do anything . An it would take a 25 amp fuse. So what's your problem ? You just go looking for fuse's ,no problem . That is suppose to be empty .

Does the heater work ? blower motor pushes air out of the vent's ? A/C compressor doesn't engage ? I'm try to figure out what you have going on there . completely dead on dash panel ? Two fuse in the central junction box F2.14 10 amp an F2.20 10 amp these power the climate control panel . Relay one has nothing to do with it . If the fuse's are good you need a new control panel .

If you are talking about the blower motor, yes.
There is a fuse and a relay in the engine compartment.

check under the hood in the fuse/relay box for a blown fuse or relay. also there is another fuse panel under the dash next to the steering column. when u take the cover off the fuse/relay box under the hood look inside the lid and it will tell u which fuse/relay controls the cruise/horn/etc. hope this will help you!!!!

The cause of your concern could be a faulty Air Susp. Fuse, Rear Susp. air Spring, Air Lines, Air Control Valves or Open/short circuit.

I Suggest you to check the following if you want to check it by your self first;

1. Check the Fuse located at rear side of truck.
2. Check both rear the Air Srings for possible cracks especially at lower portion of rubber (folding area)
3. Using water with soap, check rear both air lines and springs for possible air leak.if possible check it in different hight level. Replace both air springs if found evident of air leak.
4. Swap Rear and Front Hight level sensor if possible. If the problem transfer to front then replace Sensor.
5. Check Air control Valve fro possible stuck up, knock it several times gently and observe. If doesn't make change, check power suppy with voltmeter. If you couldn't find the problem then Bring it to BMW Service Center.

Good luck.

the fuse and relay are located in the battery fuse box under the hood, just in back of the battery and the fuse and relay locaters are printed under the lid.

there is a loose ground and or wrong size fuses for the air
if loose ground you will want to have a certified mechanic trace the grounds back to source
i dont think it could be relay but there is a way to check this
find the relay panel in the engine compartment open it
find the relay that says air conditioning
pull it out
now there are numbers on that relay
in that same relay box theres relays about 6 to 8 of them that look similar to the air conditioning relay
this is where the numbers come in if the numbers match switch with other relays
mark the air conditioning relay with black marker or nail polish so you know which relay is which
if its the relay thats bad the new relay from the relay box put in its place will work fine
put the old one back in the slot where you took out the other relay out of and then proceed to dealer to purchase new relay for your vehicle if the relay was the problem
