New here. Question about what fan noise could be..
Hi, I'm new here. I got a 92 325i a couple of months ago, 80K miles, great shape.
Anyway, I was having a couple of problems and so i read a bit on this forum and got a bently and went on my way. I fixed 3 broken parts in the sunroof and am waiting on some grease so it slides better more easily, but now it closes and opens perfectly. I changed out the AC microfilter, the old one was disgusting. I also took apart the interior door panels to fix some bubbling and had a piss poor time trying to get them fixed, i have one more to fix that's bubbled really bad, does anyone have any suggestions for that?
The problem I have that I can't solve is this, I have an electrical short that drains my battery in 6 hours or so. I know the battery is good, the alternator will generate plenty of power (I just disconnect the battery cable every time I park somewhere, it looks real cool popping the trunk to disconnect the battery cable and reentering my radio code and time for the OBDI).
Anyway, with the battery connected, there is a fan that runs that's noticeably loud. This is without the key in btw. I took out my air intake right up to the mass airflow sensor. The fan noise seems like it's coming from INSIDE the air intake, or at least the noise carries very well through it. I'm pretty sure this fan shouldn't be running without the key in so I think it's the culprit. What the F fan could it be back there?
If you want any more pics or need some kind of test, message me.
I've also disassembled my sunroof and successfully put it back together, so if you need any help with a sunroof fix for a 92, message me i'll be glad to tell you what I did.
Cheers - Nate
