Hello all,
Sorry if this has been posted before. I have a 2004 Tahoe Z71 with 190k on it. I started noticing that when I turn the truck on, it is in 4hi or 4lo. When I pushed the switch to put it back in 2hi, the switch would blink and then stay in either 4hi or lo. After multiple times it would finally go into 2hi then "service 4 wheel drive" would show up on the dash. After reading some forums and talking with others I found that the switch could be going bad, so I bought a new one and replaced it. The problem stopped for about 2 days or so and then same thing happened. This time when I pushed the switch to put it in 2hi and it went in 2hi fairly quick. It has been about 2 months since I have had a problem. Today I turn the truck on and the switch light is red and is in neutral. I pushed 2hi, 2hi lite up, then "service 4 wheel drive" shows up on the dash. I can put the truck in 4hi or lo and it is a hit or miss whether or not its a nice and smooth transition or clinking and not so smooth transition. I am not a mechanic by any means. I can get around with in reason, I normally do my own maintenance. I don't know all the acronyms so if you could put things into layman's terms that would be best. Thank you in advance for helping
