Q&A

Only if you think that they are good. it sounds like you have either a leak or non-functioning temp door. The best thing to do is to have a thorough A/C inspection, which includes a pressure check and a complete check of the interior controls. Then you will have a clear way to deal with the problem with your A/C. Adding some R134 is pretty much guessing. Most vehicles don't lose their cooling capacity with out some kind of problem. Good Luck!

It sounds to me like you need to change the in-cabin air filter. It is located behind the glove box. Mine was completely clogged and when I replaced it the A/C started blowing twice as hard.

My 2003 has done the same thing started in 09 cabin filter from dealer 40 bucks did not do a thing. Gotta be a part in the dash unit I? surpose.

NO WAY GO TO A REAL SHOP.

This is not an answer but a clarification I think. The issue is that the floor pressure is nonexistant. All the other vents have plenty of pressure. You can hear the blower pushing air somewhere behind the dash, but it's not blowing onto the feet when the feet setting is selected. Really a pain in the butt whenever it's really hot or really cold. Going to take it to the dealership to find out what the problem is and I'll post the answer once I get it.
