Hey community of rev I bought a 1986 e30 about 4months ago and I've been doing everything myself for the most part but I'm stuck with this issue my blower Moter doesn't work!......but the other day I picked up a crack free dash for 30 bucks;D and pulled my old one out I also bought flex tubing because I wanted to organize all of my wires under the dash well when I pulled my dash out and wanted to try and figure out the blower motor problem (because I don't have ac but I have everything I need for it and was gonna put it in later) well to my surprise it worked!! Well I then turned it off and turned it back on and nothing😡 Can someone anyone help me get this thing working!!p.s yes the fan was working on all speeds except 1....and I noticed when I turned the car on a wired buzzing noise started it sound like it was coming from the heatercore?
