I just replace all my radiator hoses today and ripped my front clip off the car and replcaed the a/c / radiator fan. Is there a adjustment on the fan to make it faster? It is the electrialcal one in the front of the car. I have a 1990 525i. THANX!!!!!!!!
It has 3 wires I have no I dea what they are for but they plug into a three wire connector. Should be the same as your fan Da Bull. My car looks just like yours when yours was stock, complete with Glacier blue paint. LOL
I havent ever looked at mine, but 3 wires more than likely should be power, ground, and trigger from a relay, if I had to guess. I am assuming you are talking about the little electric one right behind the grills. Most every fan I've ever dealt with was just one speed. Mine seems to turn rather slow too. Guess just the nature of the beast...

The fan was not pluged in all the way so a connection was not properly established now that it is pluged in all the way it spins alot faster and keeps the a/c cooler.
