#1 of 51 99 Nissan Quest blower resistor shorts blows after replacement. by 46ts Jan 11, 2007 (1:08 pm)
I have a 99 Nissan Quest that I have replaced the blower resistor in order to get the low speeds to work on the fan. The new $34 resistor burns out after 3 days. I suspect there is a short somewhere or something is causing the resistor to overheat. Has anyone found faults related to this? The dealership said there is a second resistor for the rear air, where is that? They said by the other one, but I did not see it. Leaves blocking air flow over the resistor? Bad Bearings on the motor causing excessive resistannce? The ac does not work and I noticed that no hot air blows out of the rear air vents. Any ideas?

Members who might be experiencing the same problem might not look here in the Climate Control discussion, so I've made a new topic and moved these posts there:   Nissan Quest/Mercury Villager: Electrical Issues

we have a 98 Mercury Villager and had trouble with the A/C not working. We replaced the plug and harness that go to the A/C unit. However, it would still only intermittently come on. So we took a pair of needle nose pilers and scraped the metal on the plug itself. (the prongs) and than it made a good connection. We haven't had a problem with it since. Try that and see if it works.
#6 of 51 Villiager heating problem - van is cold by adam07 Feb 20, 2007 (8:32 pm)
I have 1998 Mercurry Villager and now it is winter it takes a longtime to warm up. No warm air comes out of the vents until I start driving for a prolonged period. As soon as I stop, vents start blowing cold air. Same issue with the rear heater. Also the car has Water Coolant smell once van is driven with the heater on for a longtime. Otherwise the car is normal and does not over heat.   Took it to a mechanic. The car was very low on Coolant water and he found a Coolant Leak from the rubbber Radiator Hose. He said this is a big job, since to replace the upper radiatr hose, will require removing lots of stuff and replacing the manifold gasket.   Does this make sense? Do I need to do all this to replace the rubber hose?   Your opinion please.   Thank You    Adam Replies to this message: steven38 (Feb 23, 2007 11:52 pm) rick_wally (Jan 16, 2008 12:39 pm)

Replying to: adam07 (Feb 20, 2007 8:32 pm) What you are understanding as the upper radiator hose is possibly not the large radiator hose but the small coolant bypass hose near the intake manifold. Ask your mechanic specifically. Unfortunately it is a labor-intensive and expensive job to replace this small hose. You may also have a defective thermostat, as these thermostats have rubber seals that deteriorate and may them defective by overcooling the engineer. That would also affect how much interior heat you are getting. If you have this mechanic do the work, I would suggest you also have him replace the thermostat. If you are losing coolant and drive your vehicle for a prolonged period, you will overheat your engine eventually. So you should take care of this soon. Good luck!
#8 of 51 97 Villager dual A/C reset code by gberlogea Jun 11, 2007 (3:16 pm)
I have a 1997 Villager with dual A/C. I have replaced the A/C compressor and accumulator and for a few weeks I had ice cold air front and back; to my surprise, now is only in the back that is still ice cold, in front being barely colder then outside! What could be the problem? What buttons I should press on the A/C controls to reset the ventilation system?

#9 of 51 2007 Quest Bad front A/C Resistor? by cadrivr Jul 11, 2007 (9:07 pm)
My wifes brother has 1000 miles on his 07 nissan quest. Front A/C has stopped working twice. Dealer has told him it may be a bad resistor. Dealer advised him to let them know if it happens again. Is this a known problem? Any information will be greatly appreciated. Thanks. Replies to this message: 46ts (Jul 16, 2007 7:43 am)

Replying to: cadrivr (Jul 11, 2007 9:07 pm) My experience has taught me that a resister will blow when there is too much of a load on it. It over heats and the element inside breaks like a fuse. In my case the blower was drawing too many amps to operate. There was a drag on the armature causing the resister to blow. I can't say this is the same for you, but it may help in trying to identify the root of the problem.
