This is by far the biggest pain in my ass. I have 3 kids who go to school and its so damn cold you have 2 wear jackets and blankets. I have replaced everything and still no heat when it worked just a month ago. If anyone has any solutions for this I would appreciate it.
Okay here it is is can only be right around 4 things.... heater core, thermostat, waterpump, interior unit... i do all my own work on my truck..... i haven't replaced the heater core yet bc its like a full day of work you have to remove the dashboard and take half the dam truck apart that for has to be the only problem i have hot air going into my heater and hot air coming out.... so the air is getting to it but not going into the truck.. so my thing for all of you is that u replace it...even if it doesn't fix the problem the vehicle could always use a new heater core.... I will update when i replace it its only about 60$ to do it yourself
I bought this Durango as a Lease return. The first summer I went through +40 c and A/C did not work. Have had the system checked and topped up. Truck has always been cold in the winter. This year it's worse. I have had the whole system flushed 3 times. Looks like I'll be ripping it apart next summer.
Mechanic checked entire system and only came up with installing a new, higher temp (190 degree) thermostat. This hasn't really solved the problem. Still lukewarm air after running at full engine temp. I notice it more on colder days, such as 30 degrees or lower.
Like the rest of the posts, the heater does not blow very warm air out and it just gets cooler if I turn up the fan speed. Also the air is significantly weaker coming out with the heater on than the A/C (which doesn't work well either). I just bought this car though and didn't realize how many problems this vehicle had associated with this model. I imagine the heater core just ballooned up which is restricting the air going though and the core itself is probably clogged like other posts reported. I will post what I find, but it sounds like the core is just a defective design.
Update from Jan 11, 2010: Core was defective. it leaked and was covered in coolant. replaced it and all it works great! The aftermarket one works good, is a lot cheaper, but it doesn't fit right so you may have soem problems. I had the problem of trying to switch back from defrost and it takes some time and playing with the knobs, but it will eventually work. Nothing big. This is a hard DIY task especially if you don't have a B man.
Its cold outside and we might as well not even use the stinkin heater...the air feels like its barely warm my blow dryer on cold is warmer than that!! not good dodge not good at all!!
The heater blows medium heat. The stealership says the heater core might need to be replace or we could power wash the system and see if it helps. This helped some. However, I'm still having problems with my AC. AAAAHHHHH
I had the A/C serviced the summer before due to lack of cold air. $300 plus. Then, during the winter the heater started blowing luke warm air. Having been around the block I checked the hoses and I new the water pump and thermostat were new from the year before, so - heater core - no doubt. Then for giggles I tested the A/C. No cold air.
The genius that designed this car put the heater core and the evaporator behind the dashboard. Therefore, it was about 9 hours labor at $95.00 per hour and about $300 bucks in parts to repair.
