Hello

[Rickmyers]

First, thank you for letting me join. Currently I drive a 2019 1500 Laramie extended cab that is more comfortable than my wife's 21 Chrysler 300. 5.7 auto. 3.06 gears and 114500 trouble free miles. That id until today. I press the engine start on the fob to get the AC going to drive out some of this west Texas heat but nothing happened. tried to lock and unlock the doors, nope nothing. So I went out and press the start button, still nothing. I figured it was the battery in the fob, changed it (making sure I had the battery in correctly, it was) still nothing. Tried the other fob same thing, no results. Checked the battery in the truck (only 8 months old) put a multi meter on it, 12.4 volts. Lights work interior and head and tail lights. It appears that the ignition switch is dead, so I think it's a fuse. However I can't figure out which one. Can anyone help with another suggestion or which fuse or relay it might be.

The battery may have the voltage but it also needs amperage to function properly so a voltmeter isn't technically a battery test. The starters are also a fairly common problem too. Welcome to the forum by the way

FY Fuse info.
Members have had issues with the RF Hub getting wet with rear windows leaking. Have you placed the FOB against the ignition switch?

Thank you for the response. Yes I tried both fobs remotley and in contact with the button, new batteries in fobs. It's as if the ignition switch has been disconnected.

Where is the RF hub located?

Thanks for your response. I used a battery tester also and it showed a good battery

Somewhere behind the back seats, I think middle.
Not sure on the exact spot, but do you have water getting into the rear window? Is the rear fabric wet? if not, then wouldn't be the problem.

My rear window has leaked, so this sounds like the most probable cause. Thank you

Yeah the window leaks. THis sounds like the most probable cause. Thanks
