Daddy, Thanks for the suggestion. My 2000 Silverado has been having a problem with not shifting in and out of 4 WD as well as high and low. I had read a few years ago that the switch box was an issue. I had taking it out and inspected it and replaced with no change. Took my truck to a shop and they said they fixed the problem, actuator sticking from non use. OK I bought that but then the problem continued. I have also been getting service four wheel drive for a few months. I check levels ect and everything was serviced per owner's manual. Last week I changed oil ect and decided to drive in 4 wheel drive and low to throw the oil around. Got stuck in 4 low.... Finally got into 4 HI and started researching again. This time I removed the switch box, removed the solder and resoldered. I replaced the switch and everything works like new. Thanks for the help! Steve
