If you are talking about your Nitro, Chrysler uses an electronic mixing valve, to control the temperature entering the cabin. There is a small electronic motor that moves this valve, via a plastic gear. Sometimes the motor fails, and sometimes the plastic gears can strip. If you turn your control valve from cold to hot, or hot to cold, and you hear clicking, the gears are probably stripped, not allowing the valve to mix. If you turn the heater fan down, you should be able to hear the motor - it should be on the passenger side, behind the glove box. At least, that is where it was on my Jeep. Good luck. :cool:

I totally agree here.. You see.. It looks like they are not allowing the valve here to mix to produce heat. Maybe there is something wrong on the chrysler.

Heater issues

hello i have a 2008 nitro r/t and the blower motor stops working at times. i have been working on this for a month and i have caught it when it stops and checked it. have no voltage to the blower motor, or the resister pack so i thought it was the hvac control unit and bought a new one but it does the same thing. now i have found out that the blower switch power plug on the rear of the hvac unit is loosing voltage. wiggled all the wires and thinking there is a loose connection but nothing happens. does anyone know where that power comes from or have a wiring diagram please. dont know if it comes from another module or the pdm under the hood or where. i looked for a relay but the only relay that says blower k8 and it says rear blower. that makes no sense to me because there is no rear blower...thanks

Welcome to the forum. I am sorry to see that you joined under these circumstances. The blower motor is controlled by a resistor, and it seems to me that the resistor has a weak spot which may be causing an intermittant short.

2007 was the first model year and I would have thought that any bugs would have been worked out by 2008. That being said, I can't really answer your question.

Is it me or do the majority of nitro issues occur in 2008 models ?

Sent from my GT-I9000M using AutoGuide.Com Free App
From a Factory & Recall perspective it was 2007, Nitros first year in production had numerous problems, but it's best sales year by far. By 2008 most issues had been addressed in production but future sales had already been damaged with Recalls, Reviews, Word-of-Mouth, from its first year. As far as design faults they remained since no real changes were ever made from the first years model through the end (2011). For myself I am still pleased I ordered my 2007 R/T, but thanks to info here it received every recall and TSB I saw, by my Dealer all under warranty. As in most cases the final year of 2011 production must have been the best year to have purchased a trouble-free new Nitro!

Funny you mention this, my blower fan just stopped working in hi. works okay at the other speeds. Is it the switch or this resistor you mention? are they computer controlled? another odd thing happened a couple of months ago. came out of home and popped the tailgate. the radio started playing...odd!!

When one of the speeds stops working. 9 times out of 10 it is the resistor. This happened to me on both my Jeep Liberty (2x) and my Jeep Commander.

Where is the resistor, is it accessible and owner replaceable? [in case other speeds start failing]

Radiator vs. coolant?

My 2008 (but purchased in 2009 with 26 miles) Nitro was blowing cold air on the drivers side, but had heat on the passenger side. Brought it to the dealer, who has been the ONLY one to work on the vehicle since I bought it new. They determined the problem was a blockage in a radiator hose - the coolant was like mud, which they said was a result of an interaction between the OE G-05 coolant and the radiator. They also said there was corrosion throughout the cooling system, and that I might need a new heater core, radiator and thermostat :( . My warranty was up earlier this year and I only have 45,000 miles on my truck. My question: has anyone ever heard of this type of problem? I researched it on the Internet without success and I'm thinking there is something very wrong when the dealer makes me pay to fix a problem for a reaction between their coolant and their radiator. They also suggested I sell my truck to them asap so they can auction it off. Can anyone help? Thanks!

Welcome!

Usually this issue is caused with improper setting on the dash or the distribution baffle under the dash. Sure the radiator or heater core could need flushing or a change of coolant might be a good ideal, but that would be because of no heat. Sounds like a Dealer taking advantage of you to me. Find another Dealer or even a repair shop to get a second opinion!

Also it appears they want you to buy another vehicle from them and steal your Nitro that you think needs major repairs. With only 45K miles your Nitro would be considered having low miles.

Hope you don't follow their suggestions and find another source to just have your heater work on the drivers side. I had the same issue when my Nitro R/T was new and it was covered under warranty, and it was with the distribution door/duct-work under the dash near the floor. They ordered all new parts and installed to correct a know factory issue at the time.

Hope this helps out and please let us know how it works out for you, and Good Luck!

Welcome to the forum. I agree with Rick 100% here, and it really bothers me when I hear things like this. I am lucky enough to have a good dealer that I can trust. It could be a bad blend valve, or one of the doors in the ducting is stuck. If your dealer has serviced your truck since new, they would know that it is the original coolant. Get a second opinion; and then initiate a complaint against your dealer, through Chrysler. At this jesture, I'm sure that they would abide by your wishes. :eek: Good luck.

Thanks!

I will definitely bring my Nitro to a different dealership and see what they say - I appreciate the advice! I'll let you know what happens.....

Truck was in the dealership this week with intermittent shudder when shifting. While there they noticed the blower issue mentioned above. Not resistor but switch. quoted $250.00 to replace, no thank you...

Here is the switch from ebay:

07 10 Dodge Avenger Sebring Climate Heater Control 05058100AE Original | eBay

They are charging you way to much in labor. To get the dash center stack face plate off, do the following:
1. Remove the rubber pad from the top cubby, to expose 2 screws. Remove these screws.
2. With a panel removal tool, or similar, insert it between the center stack cover and frame - pull forward gently. Work yourself down a little at a time, alternating sides. The cover is held on with metal friction clips.
3. When you get to the bottom, you will need to put the shifter in Low, for clearance. Make sure your E-brake is on!
4. Once the panel is free, unplug the power port, the heater control and the switch strip below it. The heater control module is screwed to the back of the center stack panel. Switch the old one for the new one, then put it all back together.

Simple way to save almost $200. Good luck.
