Re: A/C always blowing hot on 2006 Lincoln LS V8

Welcome to the forum!

So her car only has one blower speed - full (and off)? That sounds like the blower motor controller. This would be independent of the issue of only having hot air from the vents though. That could the DCCV or possibly that the A/C is not working/low on R-134a. With the A/C set to be on, or the system set to Auto and a cold desired temperature set, does the A/C compressor clutch engage and stay engaged for several seconds?

With the 2798 code there's a good chance the DCCV has a fault (or the wiring to it).
