SOURCE: I need to replace the fan belt. Which pulleys does it go around?

Hi there,

My brother in law and I changed it without taking anything apart except the fan cover, what you'll need to do is gently use a crobar to release the tensioner pully directly below the alternator, and jam it a bit, then slowly release the old belt, if it's as worn as mine was you'll be fine. Then simply run the new belt starting from the bottom up. There's a great diagram on the weblink below.

Where is the cooling fan relay-there are several under hood in relay box but they're not labeled


You are correct the high speed relay is bad. The cover to the fuse box and owners manual should tell you the location

it has a switch, (marked fan speed)
the switch is bad ,if low speed are dead. and high are good.
or wiring to it , the motor or the fuse.
even a cracked fuse, change the fan fuse to a new fuse.

Ac only gets cool when car is moving


Walk around front and make sure the electric fan kicks on when you turn on the air conditioning.
If the electric fan is not kicking on, the most common failure point is the relay. I have never worked on a fan on an e46, but a quick scan of the forums indicates that on this car, there is no relay but there is some sort of control box attached to the fan that turns on the fan based on a signal from the DME.
The complete fan with control box is very expensive, but one fellow reported fixing his electric fan problem with a new fan motor that he got on eBay.

The fan stopped working for the rear AC/heat in our 2003 odyssey. Checked 40amp suqare fuse under hood and it tested ok. Is there a fuse or breaker for the rear fan motor?


The large fuse you checked is for the rear fan blower motor. The fuse you need to check is for the fan motor relays and rear mode control motor. It is fuse No. 3 (7.5A) located in the driver's under dash kick panel fuse box.

If fuse No. 3 is blown and you replace the fuse and it blows immediately, you'll have to check the five relays and the mode control motor all located near the rear A/C unit in the right aft sidewall. Most likely, the mode control doors have become jammed and that is why the fuse blows. The doors shift air from overhead vents (cool) to floor vents (heat).

If the fuse is fine, the trouble is probably with the blower motor itself or the wiring to the blower motor is broken, or there is a bad ground.

AC blow fan in not working. tried to find fuse no


Try looking under the hood. There should be a power control unit with fuses and relays that control the AC. If you suspect it is a relay take on from another source that isnt detimental to the operation of the engine and swap it over. If your AC starts to work then that is your problem.

Heater fan regulation


2002 Grand Caravan. The rear heater also has a resistor for the fan speed control.(3 speed) It is located under the rear passenger side plastic cover. You can take off the rear tail gate lower plastic piece and this will let you pull out the side panel. You can reach in and take out the two screws that hold in the resistor and unhook the wiring adapter. You do not have to take off the whole side panel as you can reach in from the back. The resistor unit can be bought at you local dodge dealer.
