Chrysler GrandVoyager Fan Motor Causing Overheating Issues

I had a similar issue with my 2010 Chrysler Town & Country diesel last summer. The overheating symptoms matched exactly, temperature spikes during slow traffic despite the cooling system appearing to work. The electric fan was indeed the culprit, but not the motor itself. After inspection, the problem was traced to corroded wiring connectors between the fan control module and the electric motor. The cooling system would work intermittently because the compromised connection caused the fan clutch to engage inconsistently. The repair involved replacing the entire wiring harness for the electric fan assembly and cleaning the control module connections. This was more extensive than just swapping out the fan motor but solved the overheating issue completely. This is considered a serious repair since overheating can lead to engine damage if not addressed. The electric fan is a critical component of the cooling system, especially in stop-and-go traffic when there is no airflow through the radiator from vehicle movement. Based on your mileage and symptoms, I recommend having the wiring connections and fan control module tested before replacing the electric motor. The intermittent operation often points to electrical issues rather than mechanical fan failure.

Thanks for sharing your experience with the fan motor issue. Good to know it was just the wiring harness and connections causing the problems with the cooling system rather than the entire fan assembly. My GrandVoyager has been running fine since the repair, with no more overheating issues even in summer traffic. Can you remind me how much you ended up paying for the complete fix? Also curious if any other cooling system problems have shown up since getting it repaired. Sometimes these electrical gremlins can indicate other developing issues.

Glad to hear your GrandVoyager is running properly now. The electric fan repair on my vehicle was straightforward, it cost 95€ to fix the faulty cable connection. The mechanic found corroded wiring at the plug connecting to the fan control module, which was causing the intermittent cooling system problems. Since getting the electric fan connection repaired, my cooling system has worked flawlessly. No temperature spikes or issues with the fan clutch engagement. The engine cooling remains stable even during extended idle periods in traffic. Its been over a year now and I havent experienced any related electrical problems. Regular maintenance checks show the cooling system is operating as designed. Getting the wiring fixed early likely prevented damage to other components like the fan motor or control module.

I finally took my GrandVoyager to a different mechanic last week after reading about your similar experience. The radiator fan issue turned out to be exactly what you described, corroded wiring harness connections causing vehicle overheating problems. The repair was cheaper than expected at 120€, mostly labor costs for cleaning connections and replacing the damaged wiring. Much better than replacing the entire electric motor assembly like my previous mechanic suggested. The cooling system now works perfectly. No more temperature spikes or overheating during city driving. The electric fan kicks in consistently when needed, keeping engine temperatures stable even in slow traffic. Really glad I got a second opinion instead of paying for unnecessary parts replacement. Regular maintenance should help prevent similar issues in the future. Will definitely keep an eye on the wiring connections during future services. Thanks again for pointing me in the right direction with the diagnosis.
