I have a '91 318is, and the blower only works on high. I suspect that the rotary switch has failed. Is this fairly easy to replace?

Thanks everyone. I was hoping to order before removing the resistor, but looks like I'll have to dig it out first. And my daughter was just getting used to working a/c ......

Is there a way to get at the resistor pack without accessing the box from the engine bay?

Steve, can I tell which resistor I need by VIN #, or do I have to dig out the resistor to make sure. It would be great to have the part before disabling the blower.Originally posted by blunttech View PostComment

ha, dash will be easier than pulling the engine!Comment

Just buy an S50 so it will be worth pulling the engine.

Yeah, no need to pull the engine. If anything, some pull the intake manifold to do the blower fan and/or wiper hardwareMtech1 v8 build thread - https://www.r3vlimited.com/board/sho...d.php?t=413205

If I had an M20 I wouldn't need to pull the engine. My "problem" is that I have an s38 and its a little less accommodating against the firewall. Note sig. These are first world problems.Comment

When this happened to me, it ended up being the brushes in the blower motor wearing out and not the resistor.Comment

Would bad brushes cause the motor to run only on the high setting? I would have thought the brushes would have affected all speeds.Originally posted by E30Gus View PostComment
