Hi Scotty,
I have a 2010 Dodge Ram 1500 with the 5.7 Hemi with 164,000 miles. I have had the truck for 6 years now and love it. It is having issues with the climate settings in the cab. I just replaced the heater core and I had hot heat for a while. Then one day I noticed the air was only blowing hot on the passenger side and luke warm on the drivers side, after the new heater core. Same for the ac. It sometimes will blow colder on the passenger side than it will the drivers side. I have replaced the thermostat, water pump and all the actuators are working properly, sometimes it will work or won't work until I switch where the air plows from defrost to on the floor etc. What could be causing this problem? Could it be the climate control module switches? I have no clue.
Thank you,
Grayson Laird
Your going to have to scan all the modules in the car to find the problem......
