Having trouble getting a fan to run. it will run with the scanner commanding It but not with the CTS coming up to the set temp. I have tried every setting i could think of or find on google, thanks

Can't look at your file. What year is the truck?
99 i believe. pin 42 works with scanner just not thru tune
Well, I'm new to HP Tuners but you have it set to No Fans.
The other thing that will help is give the fans a change to run for a little while. Set the on temp 5 or 10* higher than the off temp.
You need to update the OS to a 02 to get proper E-fan operation. 99-00 OS won't operate them correctly. Some 01 OS will and some wont. So most just update to 02 to be sure. For other particulars you need to state whether you are using an OEM fan harness or an aftermarket one. And if aftermarket then you need to say if it is the type with 1 wire added to the pcm and 1 wire to the A/C compressor or 2 wires added to the PCM.
if i did mine over again i'd use the 2002 tahoe os to run the fans and have the ability to use e85 if you ever want to burn corn. otherwise like stated above any 2002 os will do the trick.

The older 99-00 OS's can be made to work also, they are the same OS's that were also used in Fbodies and C5's from the same years that both had 3pin AC pressure sensors and 2 cooling fans.
