  • Why can’t u people show more of the engine compartment fuses and relays

  • Hello BMW X3 2005 2.5 ltr as soon as I start the engine the fan starts running. I have changed two temp switches located in lower hose another one under the intake, water pump and thermostat. Also, lower radiator hose is cold and upper turns hot. I cannot find fan regulator to change that might solve the problem. Can anyone help me please.

    • It’s common for the fan to run whenever the ac/defroster is on. Try turning all the heat-a/c controls off.

  • Running lights on driver side losses voltage after being on for a few minutes. Is there a relay for them or am I needing a new harness?

  • Is the fuse for the alternator / a charging relay not in any of those boxes? Is it straight on the alternator in these cars? Or is there a term im not familiar with that will help me find that specific fuse?

  • I’m looking for the alternator fuse as x3 is a “lil beotch”!!

  • Can’t figure out why my sunroof,windows,AC,light indicators ( signals, headlights) heated front seats,mirrors and probably a couple other things won’t work. I changed the general component module and put a new battery in it the reset it . There was two different codes to choose from when it was hooked to the computer has that got anything to do with my hair being pulled out 🤬

  • cual es el fusible del maletero,,, no abre
