SRTurbo04 Posted May 8, 2021 Report Share Posted May 8, 2021 08 Grand marquis ls, AC won't turn on. New compressor 2 years ago. I can hear the compressor click on, but cant get cold to come out(used it 2 days ago was fine) Also when just on vent the temp never changes it stays hot, any ideas? Seems compressors kicking on and off. Lines going into car are ice cold. Some sites saying blend door actuator, does that sound right? Anyone wanna make some money and fix this? Cant be with out ac ahh Quote Link to comment Share on other sites More sharing options...
cstmg8 Posted May 9, 2021 Report Share Posted May 9, 2021 Sounds like you're right. It isn't switching the airway from hot to cold. Unfortunately, it looks like there is a lot of dash removal involved. Most people online seem to think it's not a tough job though. Quote Link to comment Share on other sites More sharing options...
Geeesammy Posted May 11, 2021 Report Share Posted May 11, 2021 You need A/C gauges to really do much. you can remove a blend door actuator and manually move it, but generally you should be able to visually see it move if you can access it.

Rick-n-Columbus Posted May 11, 2021 Report Share Posted May 11, 2021 It could be the EATC o-ring failure common on the control units. I had the same thing happen on my Marauder. https://www.mercurymarauder.net/forums/showthread.php?80673-EATC-o-ring-repair-How-to-with-pics Quote Link to comment Share on other sites More sharing options...

Thats not an issue im having fortunately as all vents change. Quote Link to comment Share on other sites More sharing options...
spectragod Posted May 18, 2021 Report Share Posted May 18, 2021 I’ve changed out a few blend door motors, I recommend a oem part, less failure rate than the ones that are guaranteed for a lifetime. That said, I can beat the book time by a lot, and it can be done without the whole dash coming out. It does take special tools to accomplish this with the dash in the car, the snap-on man loves me.
