the a/c blower stop working in my bmw 325i, how i fix that
Would need more information to help with this issue. Do you mean you blower fan has stopped working or only works on one speed? Or does it no longer blow cold air with the blower is working normally?
well the blower fan was working in one speed and was in the number 3, but now the blower fan just stop working.
In the E30's, dirty resistors in the firewall were the culprits. Cleaning them with electrical parts cleaner, the non- flammable version, usually did the trick. As for the E36, similar parts may have been used. It's worth a try.
Check the fuse first.
use direct current to test the blower and if it does not work, replace it. If it works you'll need to check the rest of the system.
Michael is correct you have a problem with you blower motor resistor. You will need to replace this in order to get you blower fan running agian on all speeds. You will need to take down the drivers kick panel and knee bolster. It will be towards the bulk head on the heater box. If you can't find it go to pelican.com they have a DIY instructions on how to replace it. You may still have to replace your blower motor but I would start with this first. Good luck and hope this helps.
could you tell me where the fan motor is located, and how to access the connections to test it ? thanks
we found the resistor plug, and have current to all 4 prongs, i assume are the 4 speeds to the fan, but without knowing, cannot find an access point, to test the fan blower, thanks again
The blower doesn't have 4 speed. The resistance makes the variable speeds. If yours is a digital a/c of course. The blower is under the right side of the dash, you will have to take some cover or the glove box to acces it. You will notice the shape of the motor when you see the a/c box.
i'll look, on the right side, ... thank you
Yes, passenger's side
we found the fan blower motor, and tested it, sadly, it has to be replaced. Thanks for your time, and suggestion !
