98 Grand Voyager A/C

Been noticing a couple of things about the A/C recently. Doesn't seem
to be cooling much at idle or in heavy traffic, but cools COLD at
30+mph. Never noticed until just recently that I'm seeing moisture
coming out of the A/C vents. We've never noticed that in the 4 years
we've owned it. Don't know if that's abnormal or not. Replaced the
battery 6 weeks ago, but still a little sluggish when starting first
thing in the morning. Don't have any idea how tight the serpentine
belt is supposed to be. Had the belt replaced about 18 months ago.
I'm wondering if that belt isn't tight enough. I'm not a mechanic (or
really mechanically inclined) but $ is kinda tight and don't want to
pay a big bill for anything. Any idea how much flex there should be
in that serpentine belt? I can probably find it within my abilities
to tighten that belt Any ideas? thanks

 

i'm also a amauter so just listen me and if you like follow my idea.

there must be soem books on free libraries about different cars and they
try to tell you how tight the belt should be. In my oppinion, it should be
tight enought not to make any noise (slipping). If you get some moisture
out of the A/C vent, yyour system might be clouged. AC collects lots of
water when you are using it, and it dumps it from the passenger side
firewall(many water lakes under the cars are just becaue of ac). If te
drain hose is clouged, you need to open it one way or other, or it will
dump the water in the car soon. basic orgigin of the problem is the leaves
of trees clouging the drain plug.

check the water level or the radiator. Your heater core might be leaking.
it is very close to the evaporator(?).

In addition, try to use recyling mode. In my 89 car, if i use in
"recyling the air mode", heater core does not get any hot water anymore so
AC becomes much more stronger.

 

Are you sure the mist is moisture and not refrigerant?
I've had to replace the evaporator twice because of leaks.
If you wait two long, the compressor will seize. Then expect
about $1200 to $1500 bill to get it all fixed. I would
turn off the AC and take it to and AC shop ASAP.
