Fan not turning on with A/C
Posted: 2022 May 23, 19:26
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!
