TYM Cab owners beware!

[Dunkinboom]

So outside temps are rising. Hopped into my T474 shuttle shift cab and turned on the AC. AC light didn't light and no blower. No power to any controls or radio. WTF! 2yrs old and 83hrs. Checked fuses under the hood and dash fuses-all ok and have power to them. Waited for Monday to roll around and called the dealer-told him what was going on. He said-ya the tractors 2 yrs old but electrical is only covered 1 yr. I explained its a 45 minute trip there one way, and if its not covered, where does the harness run and if there is another fuse. He said, no other fuse, but under the cab is a 10awg 2 wire 'water tight' connector that is probably corroded-that powers the upper console. Found the connector and was full of water. Really? There is a similar connector next to it that is bone dry. At least he gave me what to look for. He said you don't need to replace the connector and all they would do is cut out the connector and heat shrink the wires back together-which is what they would do not under warranty. So I did this and wrapped the harness up. Dielectric greased the connector next to it-everything works now. I seldom use the tractor in the rain and it has never been submersed.
I figured I would give anyone some insight of what their problem may be if they run into this issue.

Interesting that the dealer knew exactly what the problem is. Also kind of sad that they didn't fix it since it's a known issue that came from the factory like that.

Could you describe WHERE under the cab it is located? I haven't had a problem in 490h yet, but who knows?

SOP for me is di-electric grease in ALL Molex connectors, gasketed or otherwise in the tractors and vehicles. Just something I do as a habit.

Looks so much like an automotive Tyco connector for interior of the vehicle. Exterior types have a 3-ribbed connector gasket to seal off when the two connectors join to make it water proof/resistant.

Why did TYM go so cheap to save $8. Who knows.

Sounds like the dealer is full of it.

Warranty is 2 years (6 for powertrain).

Go directly to TYM.

Mines a shuttle shift-don't know if HST is the same-probably is. But under the floor of my clutch pedal (LH side of the console) are the 2 connectors. They look similar but the one with the 2 wire heavier gauge wire was where my issue was.

My orange rubber seal was still in the connector
