Easy to replace HVAC controls, but make sure you have the right connections on the back!
Replaced the original perfectly. The fan speed switch had failed on the original controls - too much dust and dirt from taking care of horses.
NOTES: Some controls look the same look the same on the front but don't have the same electrical connections on the back. Most seem to use just one connector, ours has two. Also, the truck's body computer takes a minute to "learn" the new controls. Don't worry if all the features don't respond immediately.
After pairing it to the truck. Ran it through all controls worked then tried adjusting to defrost and it didn’t work. Had new servo motors. Typical Ram electronics.
