94 Merc Villager.. air conditioning is working, but very feeble. Mechanic checked pressure of freon, said it's up around 30, which should be fine. I have shut down rear seats unit in case it was going back there. Any ideas what to look at?

When I set my thermostat to heat at a normal temperature range of 75-85 degrees it will work for several minutes, then goes cool. If I turn it to 90 degrees(max) it heats fine. I have had it checked by an independent garage and a Nissan dealer by computer, to no avail. SUGGESTIONS!!

Nissan Quest 2000 GXE - no heat! by vrm

Even after my engine has warmed up, I dont get any heat through my front vents.
 
My minivan now has 116,000 miles. Two years ago I replaced the timing belt. At that time, I did replace the thermostat along with all the seals + water pump etc.
 
Any ideas what I should check or repair? Is this a common problem?
 
Thanks!

My 94 Villager was putting out no heat and a thermostat did fix it but look at hoses, heater valve and heater for blockages. This is the first place to look. Might have to see if heater switch is actually doing anything.

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!
