1999 chevy blazer. Changed my fan blower but the new blower has 2 electrical input. My old blower had 2 on a main connecto and a separa 3 rd one that looks like a ground. But I'm thinking it's something else because my compressor clutch now doesn't want to engage? Does anyone known I'd that 3rd connector has something to do with my problem?

I cant really say without seeing it, but according to electrical schematics there is just a power and ground wire connector on the blower motor. Did you disconnect the A/C low side/cycling switch. I am assuming this is a S/T Blazer not a full size tahoe.
