Blower & regulator diagnosis
I have removed the blower and regulator from my friends 94 e320 and I have a few questions. After replacing the 30A strip fuse because it had a crack down the center, I could see the motor trying to spin. I could spin it and it would stay spinning, but at a very low speed. I removed the 3 wire connector and had 12v on the red wire and also had the 1-8v on the yellow wire. I did not check the black (ground wire) at the 3 wire terminal. (Should I have) I jumpered 12v and ground to the blower and it ran fine. Does this mean the problem has to be at the regulator? I understand the regulator grounds the blower. I would like to order the new parts and get it repaired this weekend. I just need to get these questions answered before I can move on.
Thanks, JOHNT |

blower motor problems
I have an 89 300se and I know it is not the same as your e320, but I had problems similar to yours. My mechanic checked all voltage and everything seemed to be within spec. He took it a step further and bypassed the regular similar to how you have described and instantly it blew like a brand new unit. He replaced the regulator and voila, it works fine now. You might check on the net on places like Importec.com, slaccessories.com, ************************, etc. for a better price because the dealer will overcharge you probably by as much as $100 like they were going to do to me. Good luck. Scott
