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.

It looks like there's 2 possibilities for this. Either with or without automatic climate control. That may be the difference. Check out the pictures on rockauto.com. My other thought is someone else has been down this road before you with a ground issue and "rigged" it up to work. HTH. -Jim
