My amp was recently installed and when the car is turned off, the amp and fan are still running. I have to pull the fuses out. What do i do!? Thanks

I would say the relay is bad. If you're handy with relays they'e fixable.
You could go to youtube.com and search "Repair Car Relays"
Otherwise replace the relay.
Hope this helps.

Fan motor bearings gummed up or bad. When you disconnected power plug may have bumped fan enough to jar in into working. Probably must replace motor.

Well as a guess the reason he pulled the fuse was because the fans would not shut off. The next thing to figure out is whether or not it is the fan switch or the thermostatic switch. You will need to test both of them with a multimeter. The thermostatic switch will need to be tested for resistance (Ohms), if tbe circuit is open then the switch is bad and is continuously running the fans.

The amp is overheating it doesn't have a built in fan. This will be more occasional in the summer months. The best solution is to build a box and buy a few computer fans, install a fuse link run the positive of the fans to a remote wire and ground the fans to the chassis of your vehicle. You need a way to recirculate the air inside your amp. I've decided to remove the bottom plate of the amp, mount the amp on a board. Cut holes out of the board and have one fan flipped to pull hot air from the amp and two fans to push the air away from the amp.
You can buy the Antec and Rocket Fish fans for under $15 from Best Buy.

Look on the radiator for a switch (Physically screwed into the radiator) with 2 terminals on it.

Pull them off and short them together with a piece of wire. (Jumper) If the fan runs your thermostatic switch is bad.

The switch is a real common failure.

If the fan does not run... check the fuses.

If fuses are ok then check the fan winding for resitance with an Ohm meter.
No resistance = burned out fan motor

Thanks for using FixYa!

try the blower motor

just check all the fuses. if not take out fan and use a jump wire to see if it works and if it doesnt well you already have the job halve done. replace it.

Which fuse are you looking for? There are six fuse panels for an E39 BMW
Fuses F1 - F45, fuse panel 1, glove compartment. Twist white plastic retainers 90 degrees and pull down from top of glove compartment.
Fuse 22 (30 amp) is aux fan high speed relay(K22)
Fuse 7 (20 amp) is engine cooling fan normal speed relay(K21)

Have you had any recent electrical work done, including installs of new radio, bulbs, amplifiers or the such. Something is running when it shouldn't be, obviously, but what? The easiest way to go through this with fewest headaches is to start pulling fuses and taking readings to determine if that circuit has the draw. At least this will narrow down the list of culprit. You sound like a pretty sharp guy, I'll let you take it from here.

check the fuse box and make sure there is no loose connection there. also check the wire that feeds power to that amp. good luck
