AC doesn't blow as hard on 2003 Nissan Murano

The ac does not blow as hard. I took it to AAA repair shop. They piut a little freon in it and sent me home. I could tell on the drive home from there that it was still the same. AC is cold, but nothing changes at different temp. settings. Puttin it on "auto" at a low temp used to blow you out of the car. Do I take it back to same shop?

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.

I agree - same thing with mine. You can do it yourself with an O'Rileys store brand filter for $15!, or have Nissan do it for $75.

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.

You described my problem exactly in my '03 Murano. It blows loud but not hard. Mine also fixes itself, and only occasionally will become problematic. I've noticed it mostly happens when on long drives when the AC is able to finally achieve temp (I live in Tucson, AZ so it takes a while). Did you ever find the reason or did the dealer figure it out?? If so, what was it and how much did it cost? Is it possible to fix yourself? I've been perplexed for years on why my car does this. Thank you in advance for your reply.
