We just had a similar problem diagnosed as a corroded connector on Left Front Strut Tower in the engine electrical harness. This was after a faulty diagnosis and replacement of alternator. Heard the clicking and many display lights and climate control cycling on and off. Transmission also disengaged at one point (in an intersection). Hope this helps you if you have not had the problem fixed yet.

Help??? My van is currently in the shop and there is something wrong with the front end. Had over thousand dollars in work done and still not fix. After making a turn either left or right, van doesn't straighten out, continues in that direction. Repair shop doesn't seem to know how to fix it.

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!!

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!

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 75 1999 Nissan Quest no heat by dkeo1963

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?!
