I have a 2006 Tacoma Double Cab SR5, 4x4, automatic with ~61,000 miles. I'm the original owner and all the scheduled maintenance done. Never a problem with this truck, until now.
Over the holiday period, the road conditions were bad and I switch from 4x2 to 4x4 (at about 30 MPH) but the indicator light just blinked. It blinked for about 4 or 5 minutes and I wasn't sure if I was in 4x4. I pulled off the road, stopped, then felt/heard "the slight clunk" (as in the past) and the light stayed on. I was definitely in 4x4. Later, the road conditions improved and I switched back to 4x2 and again, the light just blinked. I decided to "let nature run its course” and after about 10 minutes (accelerating/decelerating along the way), the light final went out. Next day I tried it again and same thing happen. This is not normal.
Any suggestions on possible cause / solutions?
Love my truck but need my 4x4.
