4wd light keeping flashing

Hey guys so I have a 2003 Toyota coma TRD which I bought a few weeks ago I finally registered it and drove yesterday for 300 miles When I got home My 4wd drive light keepet going on and off and sometimes its flashes. When i got home i tired the 4wd it engages and dis engages just perfectly fine

Need some help I have no idea what could it be because a 4 wheel drive works perfectly fine

 

Is it a regular flash or sort of random? Sounds to me like you've got some bad wiring or a faulty switch.

 

Yesterday its was regular this morning it was fine then light came on flashing then went away then 2 minutes later comes on and flashes then goes away

 

So it does this without you pressing the 4wd button? That's weird.

You may have a bad switch or something.

 

I know super odd i would understand if my 4wd not work but everything is working just fine...

Which switch you talking about?

 

Okay, technically it's a button, not a switch, lol... but I meant the one on the shifter that engages the 4wd. Given that you have a 2003, I'm assuming that's what you have, not the J shifter type...

It could be that either the button itself or the wiring to it has an intermittent short somewhere.

 

This is from the 2003 Field Service Manual. Hope it helps.

 

My 03 at a manual t-case. No push button/switch.

Edit: I miss having the manual t-case. I now have a dial you have to rotate in and out of 4wd. Just doesn't seem right.

 

Good point.

OP, here is the one for W/O switch:

 

Thanks for everyone help. I finally figured it out it was a wire in the harness going to the connector of the transfer case that was pinched almost cut with all these damn pot holes and bad roads we have here im guess all the movement in the harmess kepy going on and off. The frame was swapped few months ago imagine the pinched the harness while transferring everything over

 

Ewwww

 

Nice find and fix

 

I stand corrected, I thought the j-shifters weren't available after like 2001-2 or something.

 

Nice, glad you found the solution. Wiring gremlins are never fun.
