Just bought a 2013 RAM 2500 with engine problems. Just had a Frazer remanufactured 5.7 put in it. In the fuse box, the 80 amp Radiator Fan PWM fuse was missing. Got the fuse from the Dodge dealer, plugged it in ---- electric fan will not stop running even with the key turned off. Wondering if anyone has had this problem.

One thing that you will likely discover
The HD Rams are 1 year behind the 1500s when there is a change over

When they made the first 4th Generation Ram 1500s was 2009
When they made the first 4th Generation Ram HD models, ( 2500 - 5500s, was 2010

They made a change in the Interiors & electronics for the 2013 Ram 1500s

I would have to think that the same change was made to the Heavy Duty Rams in 2014
I could be mistaken, but someone with a 2013 Ram HD model could verify or disclaim that

I don't think they changed the electronics and powertrain of the HDs in a different year; 2013 HDs still got the new Uconnect radios. They did change to radius arms from control arms in 2013 and coil rear suspension in 2014 for 2500s
