My fans have finally gone crazy....
Yesterday when I started the car from cold, the fan comes on - as the a/c was on, I thought it was normal... checked the front and only 1 fan (right side) was running at low. I turned off the a/c and the fan now goes in to high speed AND again it was only on the right side...
Drive for the next hour or so, stopping where ever possible to check the front fans - still only 1 fan running at either low or high... (so at this point in time I'm thinking great, it's much easier to fix a permanent problem that an intermittent one)
When I got home, both fans are on at high speed... I let it run till it cuts out. Then I turned the aircon on, both came on at low speed.... $#@!!
Summary:
Engine cold - a/c on = one fan on low, sometimes 2, a/c off = one fan on high, sometimes none
Engine hot - a/c on = sometimes one fan, sometimes two fan
Engine very hot - sometimes one fan on high, sometimes two fans on high...
Any ideas ? I'm still thinking that something must trigger the fans, the dme ? But the dme must get it's temp input from somewhere. Or could the relays cause this ?
The series resistor might explain one of the fans not coming on at low speed, but now the other fan is intermittently coming on even on cold starts ?? (at least fans coming on excessively is better than not coming on at all !!!)
