Hello, I tried searching but it doesn't quite answer my problem. I have a 97 318ti and the fan does not turn on when I turn on the A/C. The clutch engages and air comes out of the vents, but the fan on the radiator does not turn on. I jumped the wires where the sensor is on the radiator and the high speed fan comes on but the low speed does not. Is this in any way related? Any help would be appreciated. | | | 07-13-2013, 09:32 PM | #2 | Senior Member Join Date: Feb 2012 Location: Sacramento, CA Posts: 2,451 | Quote: Originally Posted by btrinh Hello, I tried searching but it doesn't quite answer my problem.

I pulled and cleaned some of the relay terminals and fuses and it works now. Just need to replace the HS relay. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
