weather proofing IDM

I live in Florida, it's been raining so much lately. I have been hitting a lot of puddles. I have seen videos in the past in regards to IDM's just being water logged and shorted, because they are in the driver side front tire wheel well.

My question, is there a weather proofing kit out there, or does anyone have any methods they use in weather proofing the IDM. My thought was to just gorilla tape about two gallon sized zip lock bags upside down or something. Maybe with some shop towels in it or something. If I did do something like that, could it be bad, does that thing need to breath or anything?? I know i had it tested a couple years back, so I know it's only in the wheel well like it's supposed to be with no protection from the elements that could get in.

Thanks again for any info or tips..

Jeff

Be careful trying to waterproof the IDM, it likely dissipates a fair amount of heat and too much protection oils cause it to overheat.

In my opinion, one of the best things you can do is talk to Jonathan at DTC and see if he has any advice or provides waterproofing services.

Let us know what you come up with.

Thanks

FWIW, mine fried from water on a perfectly clear day. Point is, it collects water over time and decides when it wants to die.

From what I can tell, the only thing that will keep the IDM completely dry is to relocate it inside of the cab. But have not seen where anybody has done this.

It's the vent hole where water starts to sip in, you could probably add a hat/drip edge on that hole to prevent water from coming in, just don't cover it or it will overheat it the circuits inside.

Thanks for the information guys, yeah very hesitant, and will not insulate it with plastic bags and towels, I assumed that there is some type of heating element to it that needs to be able to dispatch off away..

Thanks sous.. I'll give them a holler.. it would be great to be able to not only weatherproof the actual circuitry itself, but also have the box weatherproof if it can be professionally done. I think I'll save me a lot of money in the long run

I am subscribing to this 'cos I've had 2 IDM failures in less than 12 months. First one was (potentially) the original IDM that had water damage. This was replaced in 8/2019 with a completely sealed unit from DTC. This unit failed last month and was replaced under warranty by another unit from DTC. I do not know the cause of the DTC unit failing. I know for sure that the refurbed IDMs from DTC are completed sealed of with no vents like the OEM units.

It would be interesting see who has relocated the IDM to a safer (from water intrusion) location and how it is done. I would follow those instructions just to make my life easier for if/when I have to replace it again, just 'cos it is a PIA to get to inside that wheel well

If you posted it here.. your issue may have been my motivation for being proactive.. definitely a design flaw for the year.. me concern is, as these trucks get older reman idms get harder to find.. I almost want to just go ahead and buy a reman right now and just hold on to it..I have no intention of letting the truck go any time soon..
