Question about 2004 Dodge Ram 1500

1 Answer

A/C blows hot air going uphill or pulling a trailer.

The A/C on my 2004 Dodge 1/2 ton pu (with the 5.7 liter hemi) blows hot air when pulling a trailer over 70 miles an hour, going uphill (even some overpasses), driving 80 mph (I live in Texas) or sitting at idle for too long. I have had a mechanic look at it and he checked the freon and charged me $40.00. It works fine around town, but will not cool under any type of load.

You will need to change the clutch fan, under load or high speed will heat up the engine and the clutch fan should ingage to pull more are through the radiator. Also at idle with no air moving through that radiator the clutch should ingage to pull air through.

I have a 2004 hemi dodge ram 1500. The air on the passenger side blows hot air. What is this, and what should I do to fix it?


Does it do this even if A/C or cold air is selected? If so, the switch that controls the vents may be loose or broken inside so it's not opening the vent for cool or cold air. Check to see if it does this with A/C on as well. If so, consider pulling the vent assembly under the dash and finding the error.

Please let me know if you need further assistance.
