Too Tall 10 Posted April 20, 2016 I did a search for radiator fan switch, I'm looking to wire in a manual switch so I can turn the fan on high in traffic. I live in southern Idaho and we get temps in the high 100*F. My rout home is in a lot of stop and go traffic and I noticed last year my temps were a little higher than I like. The fan still comes on like it should, but I'd rather give the relay a break and just have it on for the times when I'm not moving. Has someone posted on this topic and I just couldn't find it? Thanks. Quote Share this post Link to post Share on other sites
Too Tall 10 Posted April 20, 2016 By the way, I do have the Bentley manual, I just don't trust my ability to decipher electronic schematics very well. I've already managed to kill my temp gauge and cant fix it, and I'd like to avoid frying anything else. Quote Share this post Link to post Share on other sites

Remember it was dead simple but can't remember what I did exactly, I'll have look at car when have chance and it'll jog my memory. Make sure you use a feed that's only on when ignition key turned to avoid possibility of leaving it on running after parking car up. All normal auto fan switches and whatever switches fan on after engine switch off if needed unaffected. Quote Share this post Link to post Share on other sites
Too Tall 10 Posted April 21, 2016 I had a friend come help me figure it out. You use the thermoswitch on the radiator that runs the fan control module, mine has 3 terminal stacked, I bridged two and the fan comes on. It's low amperage do i done need to use a relay for the switch. Quote Share this post Link to post Share on other sites
