#204 of 791 Air Conditioner Hissing and not cooling by 05blackquest May 05, 2005 (3:04 pm)
Our 2005 Nissan Quest has had A/C problems from day 2 and Nissan has tried to remedy the situation. The first time we were told that the freon was improperly filled(air pressure not level...moisture in the line?) This was causing the A/C to constantly hiss and then it stopped cooling. Now we have the same problem. After the repairs it worked great for a week (38degree) air. Now, it is acting up again. I have contacted Nissan again and am awaiting their call. I was wondering if anyone out there is experiencing the same problems. I love my van and I hope this is a minor nuisance that can be fixed "permanently". I will post their remedy, if any, once they do something about it. The van is only 7 months old.    Roy

your Freon was improperly filled, find another repair facility. It is illegal to use Freon in a 2005 automobile.
#206 of 791 Air conditioning compressor leaking by sockpuppet1969 May 08, 2005 (2:34 pm)
1998 Blazer. No a/c this spring (did not use all winter). Had it recharged and dye put in. Re-check a week later showed a leak in the back of the compressor. My mechanic estimated $800 to fix. Is replacing the compressor something I could do myself without too much trouble and basic tools? Do I need to replace the accumulator also?   The plan right now is to see how long the current charge lasts (i.e. how slow the leak is) and then either ditch the truck or fix the a/c cheap.   Thanks in advance.

Replying to: sockpuppet1969 (May 08, 2005 2:34 pm) The problem is how you will capture the AC that is in the system. You can't just let it out into the air as that is dangerous to you and us. If your shop can safely drain it, then yeah you could probably do the compressor, but I'd have the shop hook up the lines and recharge the system.   Yes you should probably replace the accumulator and the drier if the system is open and exposed for more than a couple of hours. If you can close it up really fast you might get lucky, but usually the dessicant gets saturated with moisture from outside air and is ruined.   If you remove the compressor and look into the ports (where the hoses go) and you see debris and bits of metal, then you have to flush the entire AC system and also replace the expansion valve.   Some people will tell you that you can replace the shaft seal in the compressor (probably the source of your leak) but the problem here is that the seal might have gone out for reasons related to compressor wear, --- so the seal won't last.
#208 of 791 $1,200 to fix evaporator? by beaton May 09, 2005 (9:27 am)
My 1999 Plym Grand Voyager (120,000+ miles) has a plugged a/c in the front (but not the back). The Dealership also said the evaporator needs to be replaced. Cost:$1,200! Does this seem reasonable? We service the van regularly there due to the many hiway miles we put on it annualy.   What causes the a/c to plug in one spot and not in another? Should they be checking that as part of the regular maintenance? If not, how often should we be checking it?   Thanks! Replies to this message: Mr_Shiftright (May 09, 2005 10:36 am)

Replying to: beaton (May 09, 2005 9:27 am) depends on whether your car uses two evaporators or not for front and rear air heat exchange. But if your system has only one evaporator, and if indeed you get ice cold AC in the rear, then the dealer's diagnosis makes no sense.
#210 of 791 Dakota a.c. problem by kramer3 May 11, 2005 (11:20 am)
I have a 98 dodge dakota with 74,000 mi. on it. The a.c. stopped blowing cold air so I added a can of 134a. It still will not blow cold air. The compressor cycles on & off & with a gague installed on the low side the pressiure drops form approx 40 p.s.i. to approx. 15 p.s.i. when the compressor clutch cycles on. Is this normal? Should the clutch be cycling on & off? Also, it is not leaking water from the drain, but I am not getting any water in the cab. i don't think i have a leak as I added some dye, & the system seems to be holding what I put in. Any ideas?

#211 of 791 Ford E-150 Vent Selector by chopper23 May 12, 2005 (5:00 pm)
When I started the Van today, with A/C on, the air was only blowing out of the Defrost and Floor ports. I cannot get the air to come out of the dashboard vents. No matter what position I put the selector in, the air just comes out of the two ports mentioned. Any ideas as to cause/fix? Thanks Replies to this message: kirstie_h (May 16, 2005 9:28 am)
