Hi all, I seem to be having a problem engaging 4 wheel drive in my truck. This is a used truck with 90K mile on it. After driving for a while, the 4 wheel drive will not engage (get the flashing lights on the dash). If I let the truck sit for a bit (1 hour +), will engage with no problems. It's tempermental, and am wondering if there was any issues with this particular years 4 wheel drive. Also wondering what checks are made when attempting to engage 4 wheel drive?

Thanks,

Matt

Maybe that the electrical plug to the shift motor needs cleaning, maybe more.
