Question about 1999 Dodge Durango

1 Answer

Windows won't stay defrosted.

The windows on my 1999 durango won't stay defrosted. The temp guage is about 195 degrees. The duct shifts from winshield to dash and to the floor alright. I'm thinking that it's maybe a ventlation problem. The book doesn't indicate a cabin filter or anything. What can it be? Help!!!

Thanks!

I suspect you're having the same or a similar problem that I have - that your heater core might have a pin-hole leak. It'd be somewhat confirmed if you're finding that you have to replace antifreeze more than once every couple of weeks or so. If you haven't been checking that regularly, next time the engine is cold, take off the radiator cap. If the coolant is up to right below the cap, and the coolant tank is shows you have coolant (and someone hasn't been maintaining this on a frequent basis) then I'm wrong. What happens if you have the leak is that every time you stop the car, the engine-heated coolant vapor rises out through the defog/defrost ducts and condenses on the cold windshield. Worse is that the water evaporates, leaving the coolant on the windshield, and it has an affinity for water - so the next time you stop, the problem is a little worse - more water on the inside of the windshield. Enough of that, and cold enough weather, and it freezes. Another possible problem is that the heater core is becoming plugged, and isn't able to move enough heated water to make enough warm air. Either one of these means that you get the priviledge of having the heater core replaced. From what I've seen on other pages, changing this involves draining the cooling system, removing the freon from the A/C, removing the dash (the whole thing) from the firewall, to gain access to the heater and A/C cooling coil, replacing the heater core, re-assembling the dash, replacing the coolant, and recharging the A/C. Standard shop time is 9 hours. Some have commented that if you're an experienced mechanically adept person, you might manage it in 6 hours. I'm waiting for the weather to warm up a bit, and learn more about the dash remove and replace process, before I take my wheels out of service.

The abs light and brake light is on the speedometer does not work until i hit 30. the tempature gauge fluxuates from 210 to almost the 260 and then goes back down to 210. What is causing these issues?


This is most likely 2 problems. The ABS/Brake light and speedo issue will be the speed sensor located in the read differential housing. The temp guage issue (and I'm assuming this is at idle) could be thermostat or temp sending unit. The fluctuation is causes by the electric cooling fan cycling on and off to control the temp. However, most of the time this fluctuation should be from about 195 - 220 degrees.

Thermostat temp guage goes to 220 degrees


220 degrees is normal operaing temperature for your car. The thermostat does not open until 195 degrees and the fans don't come on until 126 to 128 degrees. If it gets over 129 degrees and the fans have not turned on then the cooling fan system is the cause of the problem. (cooling fan, cooling fan temp switch, cooling fan relay, etc.)

Where is the temperature sensor located on a 2002 hyundai accent


okay temp is not hot enough check thermostat temp rating is it 195 degree etc. are you in a cold climate state? Maybe you need to get a thermostat of a hotter degree[four seasons 195 degree should do it]. If this is what you have (195 deg. thermo) then it might be stuck open not allowing the heat to build up. Another possibility is air in the radiator system, bleed system. This too might be of help the blend door, which is operated by the HOT to COLD lever on your climate control panel, might not be moving all the way closed to stop the cold air from coming in the mix area with the heat. Move the lever back and fourth to feel any change in heat with your hand. Put the defroster on fan on high and put one hand near the defroster vent thee other hand moving the temperature selector. Do you have some sort of heat and you can feel the difference from hot and cold, then my recommendation is to check thermo degree rating, if ok then try to flush radiator, and if that does not work --replace Heater Core. Thank you for allowing me to help you if you need me just write,Lee

Defrost and Heater causes windows to fog


If it smells like antifreeze, and leaves a film on windshield, it's probably a leaking heater core, but if not, your drain tube/passage for heater/AC duct-work, is plugged and not allowing moisture to drain out. Not 100% sure where drains are on that but, I would look real close at lower firewall in engine compartment,opposite duct-work, as well as under truck near front floor, for tubes sticking out, and carefully and gently, run a pipe cleaner or similar in & out to clean, until moisture starts to run out.

What the normal temperature operating range indicated on the temp gauge?


195 degrees is the typical high end on the thermostat (when the thermostat opens), so the temp gauge should read a max of 195 degrees, give or take a few degrees. Some people replace their thermostat with a lower temp one, such as a 180 degree one. Then the gauge will read lower (approx 180 degree max). So the range is typically from cold at start to just under 200 degrees.

Temp guage in red' dummie light on engine not hot


Sounds like a faulty sensor, if the actual temp is 195/215. The ICM is processing the information it receives from the sensor and performs accordingly. A complete diagnostic scan would be helpful in determining the proper repairs needed to correct the problem.
Good luck...i hope this helps, please rate me a fixya.

I drive about 260 miles a day. my 1999 dodge truck has been running about 210-230 degrees. i drive about 70 mph. if i slow to 55-60 the temp stays 210.


seems high to me. summer thermostats open at 185 , winter thermostats open at 195. At highway speeds , there should be more than enough air flow through the radiator to keep engine in the normal range. Your radiator might be pluged up and cooling poorly , but I suspect your temp guage might be inacurate.
