Update: I have narrowed it down to a CCRM issue.

I should've ran through everything first, but figured that the last thing I added was the Quarterhorse. Thanks for looking over it for me, Decipha, it's appreciated.

Weird. I’ll do some digging with it later tonight and if nothing else, I figured I’d wire up something like this…

Ahhh, my bad. Honestly I never pulled the stock file out before I started the project. I just grabbed the FBGI0 and started going to town.

TunerPro is cool, but I'm still set in my HPTuners ways, haha. I'll see if I can compare em tomorrow morning and see what's up.

File uploaded.

EDIT: Wow, apparently I have a few things that I need to go through when I get a moment to sit down and compare these. I'll post if I get it fixed. I really appreciate the willingness to help, I still may need it.

Some of these tables in the stock bin look pretty messed up (borderline knock, MAF transfer, to name a couple), did something happen?

I’m lost on what file you need, you may need to get out the crayons LOL.

The ecu is an MDE2.

1989 Mustang with a complete 4.6 swap from an '02 Mustang GT (wiring harness, CCRM, gauge cluster, etc.).

Drivetrain was stock last year, all functioned normal and drove great.

This year I added a Paxton blower and supporting mods, using TunerPro and a Quarterhorse with an FBGI0 definition. Tune is working pretty good, but still a work in process.

Here's the issue...As the title says, neither my low nor high speed fan will turn on with the A/C. It functions normally, otherwise and with the A/C on, it'll still cycle on and off with engine temp and the compressor still kicks on and off, the fan just ignores that the A/C is turned on. This started when I installed the quarterhorse.

I have attached the file I'm using if anybody would like to take a look at it for me.

Thanks!
