Keffer inc Posted July 23, 2013 Share Posted July 23, 2013 (edited) I checked the fuses, no luck, checked the override switch, no luck, no power at the air to electric valve on the side of the radiator. owner before me has wires all over the place too.... help asap would be greatly appreciated as I'm driving a 7 hour run tomorrow. update: Fan clutch is operational if you unplug the air line going from the valve to the clutch, it stops turning. So Good Fuse, Good Clutch, Where should I be looking next? Thanks Edited July 24, 2013 by Keffer inc Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted July 24, 2013 Share Posted July 24, 2013 The air clutch system is so simple but very hard to tell a man were to look. Quote glenn akers Link to comment Share on other sites More sharing options...
305_M@ck Posted July 24, 2013 Share Posted July 24, 2013 check the connector that plugs into the valve and see if you have 12 volts and ground. if you don't have ground at the connector check the cable that comes from your ecu because the ecu send ground to the fan to turn it on and off.

Keffer inc Posted July 27, 2013 Author Share Posted July 27, 2013 I'm only getting 3-4 volts at the air / electric valve. For now I made a by pass from the battery, to a dash switch, to the fan clutch to manually control it. I only needed it twice last 7 hour run.

staxx Posted July 27, 2013 Share Posted July 27, 2013 Check the a/c high pressure switch green in color , this turns the fan on when it sees high psi in a/c system . If switch is bad or a/c system had a issues the fan will run all the time. Quote Link to comment Share on other sites More sharing options...
Keffer inc Posted July 27, 2013 Author Share Posted July 27, 2013 I ran without the ac for the last couple days because it was low on freon. Confirmed by my brother-in-law this morning. I don't think its ac related. Quote Link to comment Share on other sites More sharing options...
staxx Posted July 28, 2013 Share Posted July 28, 2013 If the a/c is low on freon it can have high presure even with a/c off , have seen this many times. Quote Link to comment Share on other sites More sharing options...
