Radiator fan relay
Pop open the lid to the relay and fuse center, should be an imprint of fuse/relay layout. If not, consult your owner's manual, I assume it being a 2015 you still have one.
They should have a recall on the fan's failure. I have 57,000 mileage and sometimes fan stops or doesnt turn fast... same thing on my friend's Ram Promaster city exact sam vehicle he has less than 30,000. And I see plenty of complaints about the same exact issue online... RECALL RAM PROMASTER CITY OVERHEATING DUE TO RADIATOR FAN FAILURE!
This should covered by your warranty depending on mileage. Fixed the relay on mine after a P0481 dtc code. Cleared the code for about 50 miles and then my cooling fan melted right off the fan motor! Stuck with the same dtc now. Beware! I believe some of thes fans are indeed defective. Fan failed at under 15k miles.
They must recall radiator fan failure my friend had that problem and I have this problem now... the dealers are trying to rip me off saying they have to replace the fan but IMHO it's just the relay!!
There's a chance it's not just the relay. These fans are known to be defective. 3,000 inoperable vehicles currently waiting for cooling fan part on backorder (I have been waiting 3 weeks so far with an updated delivery estimate of 1 more month). Very common problem. Same fan is used in the Jeep Renegades. Thousands of Renegade owners reporting the same exact issue online.
Mine just failed at 20K miles
