redXTwedgie Posted October 9, 2013 Share Posted October 9, 2013 It runs all the time if the battery is connected. Fuse was burned when I got it, so it didn't work thru that circuit. I put a fuse in it and its running continuously. Car had alternator overcharge so I'm thinking it probably melted the bat. and switched power together on one of the relays. Replaced alternator, fusible link, combination switch, and other electrical odds and ends. Had no issues for months until I discovered the fuse. So I'm looking way up under the dash, above the fuse block, for the fan relays??? Or am I on the wrong track?? Thanks. Quote Link to comment Share on other sites More sharing options...
RallyKeith Posted October 9, 2013 Share Posted October 9, 2013 Look under the dash for a pair of I believe it is green connectors with only two connections. If they are plugged into each other disconnect them. They put the ECU into a diagnostic mode and the fan runs all the time to allert you of that.

johnceggleston Posted October 9, 2013 Share Posted October 9, 2013 (edited) also, one fan runs any time the ac is on or is supposed to. Edited October 9, 2013 by johnceggleston Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted October 9, 2013 Share Posted October 9, 2013 The fans are controlled by several relays depending on several factors. Check all of the relays in the under hood fuse box. Quote Link to comment Share on other sites More sharing options...
MilesFox Posted October 9, 2013 Share Posted October 9, 2013 The fans will run continuously if the engine temp sensor is unplugged or has an open circuit. Quote Link to comment Share on other sites More sharing options...
redXTwedgie Posted October 9, 2013 Author Share Posted October 9, 2013 Thanks for all the replies. I found the main fan relay at the top of the fuse block and swapped it out and that took care of it for now. Quote Link to comment Share on other sites More sharing options...
WoodsWagon Posted October 10, 2013 Share Posted October 10, 2013 What miles said, the failsafe mode for the coolant temp sensor dieing is for the computer to turn the fans on full. Is the check engine light on? Quote Link to comment Share on other sites More sharing options...
