At age 69 I bought my first Chevy ever. I needed a replacement vehicle and found this in our town, geezer owned. First surprise was on getting a required MO inspection was that it needed a wheel bearing and stablizer in front. Never have replaced these on any vehicle I have owned in the past, but I see these bars do break on these models. One thing i cant figure out and have not found on line is the cabin air recirculating switch. It is on outside air now and the light is lit. I get no action when I try to switch to cabin recirculation only. If it has to be stuck I guess I like it like it is, but if there is some sort of common fix. Please advise, Thanks in advance.
