Easy and safe, but soooooooo boring in comparison.

The AC sucks in my Focus too, glad to see I'm not the only one. My 05 Mustang will get ice cold real quick, but it seems like the Focus takes a solid 15 minutes to get cool in 80 degree weather.

Dealing with the (real) heat down here in the Houston area and my A/C has never had any issues. It cools down the cabin very quickly.

They can be removed. The Mountune intercooler kit has the installer remove them, tape up the connector and fix it to a safe location. Since this kit doesnt void the warranty and in the UK is even installed by some Ford dealers you dont need to worry about it hurting the car.

I miss the old R12 a/c units I had in my old cars, with the new 'ecofriendly' refrigerants that everyone has to use and efficiency standards set high I dont think a/c units in any car will be as frosty as they used to be.

You might want to use a cheap thermometer to measure the outlet A/C temp with the system set on recirculate and max. That is usually the standard dealership techs use to gauge if the system is working normally. That might help you talk to the dealer about what to expect.

And I believe your car uses the pressure in the a/c system as a trigger to open the shutter. So it is supposed to open the grills if the a/c system is struggling.

My guess would be the intercooler and its location in front of the raditor. When I added a turbo and front mount to my Contour I noted that if I didn't turn the A/C before moving, more so on the highway, the A/C would not be very cool. But let it run first then drive and it was fine. My take on this is the heat from the front mount intercooler not letting the A/C condesor work as it should.

Question- if the Grille shutters are open whenever the air is on, does that mean if you use AC on the highway the shutters will stay open all the time?

I believe they do stay open anytime the A/C is on. However, I have not been able to hold on tight enough to the hood at highway speeds to physically examine that theory.

Lol. That would explain why I can only get 36mpg or so on the highway. With the AC turned off I average closer to 40, granted not having the compressor running helps efficiency a lot.

That sounds about right. I experience a difference of about 3 MPG highway dependent on the A/C being on or off. That seems in line with most other cars I've owned in the past though, so it's hard to say what portion of that difference can be attributed to the shutters.
