Car is stupid ATM. When car gets to 3/4 my high speed fan kicks in, but my low speed doesn't. I unplugged the sensor from thermo housing, waited a minute and neither high nor low speed fan worked. I replaced both fuses with spares I had around, tried again, and still nothing. Only comes on when AC is on. How do I check what's wrong? I don't have a multimeter yet, but have a circuit light if that helps. Cheers
low fan is run through bcm, pcm sends command to bcm to turn low fan on. Do you have a aldl adaptor for datalogging?
I have an aldl but my laptop won't recognize it, tried finding drivers to no avail when I have the cash I'm unplugging the dash temp gauge and installing an aftermarket digital LED one to help know temp. And am now considering bridging connector pins 5 and 6 to get dtcs the long way
what adaptor is it? some ebay cheapie or one from delcohacking? Cause if your on it with tunerpro you will be able to see if the ecu is commanding low fan on. I could also dig out the command to send to test turning low fan on. I take it your relays are all good in the engine bay, tried swapping them around with another one?
I had them both plugged in, car got to 3/4 and high fan kicked in. I did swap it as I had 4 spares laying around and none of the 5 would let the low fan work. It was a $90 one from eBay, was ment to have full version of efilive v4 and tunerproRT but only had tunerpro eval version.
