Technically this is exactly what happens as basically the systems low side pressure can only drop so far when ambient conditions raise the high side pressure numbers. Automotive freon will almost match the degrees output to the low side pressure numbers.For instance 55lbs low side pressure will produce 55 degress at the evaporator coil One way to overcome this is reduce blower fan speed which will allow air to cool further across coils and always use recirculated air after cabin temp has come down below HOT.If all else fails install pressure gauges to high and low sides and verify operating pressure readings.

Oustide or ambient temperature will have some effect on the a/c system.,,this is to be expected..the hotter it is outside the harder the a/c (freon) works to displace the heat...if your engine is at idle, or if your stuck in traffic it will be even warmer in the cabin because there is very little air flow passing through the condenser to cool it. Same principal as the radiator for your engine coolant.
Hope this answers your question, please rate me a fixya.

No heat coming from the vents.


If it is a manual system--sounds like coolant low ie: air bubble in system. If it is ATC system, Check Codes, if no failure codes, coolant may be low--air bubble in system--most Durango's have air bleeders in system.

Most of the Gen 1 Durangos had the useless rear wheel ABS. This fuse most likely goes in the the PDC or power Distribution Center under the hood next to your battery.

How is the pedal now? Your 02 has rear drum brakes which sometimes need to be adjusted to keep a firm pedal.

If the fan is running backwards, you should be able to fell the "breeze" from the outside of the vehicle, near the radiator. Also, If you spray the outside of the radiator with some water, if the fan is running backwards, the water will be spraying out when the engine is running.

Have you checked the cowl to see that it is free and clear of leaves and dirt? You may have to take the plastic off to get down into it and sweep it out with a vac. Usually it is right under your wipers.

Overheating when outside temp goes above 90 degrees F


on GM vehicles they still use clutch fans and when sitting at an idle for a while the fan is not pulling enough air through the radiator and condensor so therefor the a/c starts to put out warmer air and the coolant temp. will rise a little bit. You could try replaceing the fan clucth and see if that helps any.
