I know the four wires I need to cut. Someone told me I need to splice the A/C in and out wires together also. Is this the case? Thanks for the help.

The PFC control of the AC is bad due to poor engineering on Apexi's part for USA cars. They still have not fixed the problem and it is now 7 years later!!!!!!!!

Some have replaced the AC fan speed switched and this has fixed it, sometime not.

Some have tried a diode across the switch, works and not.

When I replace my engine wiring harness, it fixed mine except for fan speed three.
I then bypassed the ecu so all four speeds work.

First detemine how well or bad yours works, then decide on the fix.

Also, you definitely want to try it first before doing anything. Mine has worked perfectly from day 1, all 4 speeds.

See if you actually have the problem before trying to fix it.

Thanks for all the info guys. So should I cut and splice the harness or just leave alone.
