Hello my s10 peoples. I am new to the s10 world and forums I just got a 2000 s10 4.3 auto. I’ve searched a helluva lot on a couple different s10 forums and I haven’t found anything on this topic so here I shall ask lol. My air conditioning only works on 3 and 4 and when on Either one it makes a terrible grinding noise coming from under the dash on the passenger side ( atleast it sounds like its coming from there ). Sometimes on 3 it doesn’t make the grinding noise but the blower fan is very noisey and that in and of itself is annoying. My ac blows cold on 3 and 4 despite the noise but when it makes the grinding noise it’s loud and violent like it sounds like my truck is being ripped in half lol. The only thing I can find that I think it could be is the ac compressor or clutch thing but I’m not very knowledgeable on this subject at all so please helppp!
