A friend asked me to check my coolant level. I was surprised to find that there was NO liquid in the reservoir + low level in the radiator. I added coolant today but even now the air coming from the vents is not "hot" - its lukewarm.
I noticed another thing which may be an important symptom:
When I shut the ignition, I hear a sound which can be best described as "water flowing down the pipe". This sound only lasts 6 to 9 seconds but I always hear it after shutting the engine.
Any thoughts or suggestions would be helpful. Thanks!

May be off base but you may have air in the system. frankly I don't remember how to bleed it out but worth checking out.

I agree, it sounds like an air lock. Normally you would remove your radiator cap and, with the engine running, squeeze the hoses as best you can to move the air along in the system. You should see bubbles coming out of your rad. You may get some spill over but don't worry about that. You can top up your rad and reservoir (the engine will draw more from the reservoir as needed when it cools).
#57 of 77 1999 Nissan Quest no heat
Jan 23, 2010 (5:43 pm)
I have a 99 Quest and I no longer get heat from the vents: I first noticed it took a long time to warm up and never got up to "normal" temp, but it is winter. I changed the thermostat, now I have a new issue. The vehicle heats up fine and runs at a normal temperature however, I get no heat from my vents unless I really am hitting the accelarator. Doing 55 the air is cool, I hit the gas and while the engine is revied, I get great heat. Once I back off the heat dies out. My hanes manual mentions a heat control valve being closed, but I can not find any other reference to such a valve on this vehicle. Any other suggestions?!
#58 of 77 A/C Problems with a 2008 Nissan Quest
Jun 27, 2010 (1:36 pm)
I own a Nissan Quest, 2008. It is having A/C problems from my stand point. I have taken it into two dealers 7 times and have gotten the same results. After the second dealership replaced the compressor, condenser and expansion valve and the first dealership replaced the rear expansion valve, the second dealership told me that my van compares to the other vans on the lot. There is difference of 10 degrees from the temperature of the fresh air button and the re-circulation button. I checked today and at an idle my car showed a temp of 74 degrees for the fresh air button and a temp of 68 degrees for the re-cir button. With normal street driving the temp was 68 to 74 degrees with the fresh air button and 60 to 62 degrees for the re-cir button. The temp outside was 93 degrees. Both dealerships told me that this is the best I can expect for a van that has an under-engineered A/C unit. My question is should this Van perform like this and is it undersized and if not what can I do to get someone to fix it. By the way I have a Nissan X-terra and both instances my A/C there goes to 50 degrees and 48 travelling and 60 and 58 degrees idle.

rarbaugh: The temperatures seem like they are within acceptable range. The important question is how long does it take to cool down your van? Remember the Quest has a large interior area to cool down. The size of the windows do not help with the cooling. Try running the AC on level 3 or 4 for a while (yeah, I know it is loud). Make sure the rear vents are in the cooling mode.
My 2004 Quest A/C works fine. It does take longer for it to cool down but again it is a very large area to cool down and the windows let in a lot of heat.

This is very similar to the problem we are experiencing with our '04 SL. We have been measuring the temp coming out of the vents, it ranges from 68-72 degrees (those are recirc temps) while driving. Idling it's worse than that. I started writing the temps down because I knew when I brought it in for service I would get the same "it's performing within specs" line. To compare, my husband starting taking the vent temp in his Nissan truck and it was an average of 44 degrees! So I know something is not right. Well, took the van in, they "looked" at it and added a bit of freon, determined it was the front expansion valve. Said they had to order the part. My husband brings it home and now I have no a/c at all!!!!!!!!!!!!!!!! It will click on for about a min. at a time and then stay off (just normal HOT vent air) for about 5 min. Then back to a/c for another min. and so on. I was sooo frustrated but they of course said they didn't do anything! What I had was better than this. So, now we are a week past that, in 95 degree midwest heat and might as well have zero a/c with 3 kids, ages 6, 4 and 2. It's been great. (heavy sarcasm) and the part is BACKORDERED! I gave up today and found the dang thing online and paid $40 to overnight it so I should get it tomorrow. But yet here they were making me wait!
Oh and the kicker, the service manual says it's going to take upwards of *8* hours to replace this valve because they have to go through the *dash*, take the whole freaking thing apart and it's going to cost about $800. And it's of course not under warranty. I'm just sick about it but at this point if it will fix it I don't care what it costs. Though I'm concerned after all the work you have had done and you still have problems.

I think this is/will be a common problem with Quest moving forward. I've read of other owners having this same issue as you. What's scary is the 8 hours labor? That is simply ridiculous! $800 to replace a $22 part.

Well don't let the dealer do the work! get prices, look for indy shop with lower hourly.

On another forum, an owner posted directions on how to replace the part and it seemed to work. He did the work himself. I'll post it later tonight. It did not take 8 hours.
