Question about 1988 BMW 5 Series
1999 323i w/power windows & sunroof. Ignition off, exit car, lock car. then 2 minutes to 3 hours later the windows and sr come open by themselves ! Is it something to do with the "comfort relay"? I know the remote control has a "windows down" feature when the remote to unlock is depressed twice being held down for 5 seconds on the second depression. Is this some sort of "mode" that can be reset?
This is driving my fiance crazy...it's not safe for her to park outside....

you have a bad power window relay the relay should be in the engine compartment your owner's manual should refer to it it controls both the window and, sunroof circuits replace this relay

SOURCE: Help 10 codes on 323i!
These codes will have to be cleared and the car driven through a drive cycle, maybe a couple of times, is the check engine light off? Also you should check your MAF sensor it may need to be cleaned or replaced and makes sure there are no holes in your intake tubing. Hope this helps, let me know.

I have a 1993 bmw 318i and the same problem..no power to the windows or sunroof and no lights on any of the window or sunroof switches.The ANSWER is take the kick panel of the driver side locate the blue relay next to the orange or brown relay.Take the blue relay out and either replace it or take the blue cap off the relay and check the solder to all pins.There is one or more pins where the solder has crack..just buy a soldering gun and some solder .015 diameter and re solder all the cracked solder on the pins and it is back to normal.
