Question on BMW 3-Series Electrical Problems

Hi. BMW 325i 2003. Washer fluid light always on. Sometimes the blinker indicators work but more often than not they don't. Sunroof works sometimes dashboard lights stay on sometimes, other times they don't come on at all. Air conditioner blows hot air.

Sounds like a lot of electrical problems, which could be one of a number of things. In cases like this, where there are multiple gremlins, you would want to look at a few things that affect major and multiple electrical systems. For example, improperly attached ground straps, maybe a faulty ignition switch, problems with water / rust floating around the fuse box. The hot A/C blowing is probably a mechanical issue and not necessarily an electrical issue (perhaps).

Unfortunately, I don't know where the grounds are for the items you mention, but I know where one ground is that is problematic. It is on the passenger side inner front wheel well, beneath the computer diagnostic connector. I would start by pulling that off and cleaning it and see if that helps with any of your gremlins.
