I bought a lemon Big Problem

2011 Nismo#91

Location: Florida; "the guy said I don't know if the AC works I never tried it."
That's not a red flag thats alarm bells and flashing red lights.

Unfortunately there really isn't any lemon law that covers used cars private party.

Seems like it could be some sort of short circuit with the HVAC blower circuitry. Find out which circuit is pulling too many amps when the AC is running is the start point then check that circuits wiring. These kinda problems are a pain to trace down and that's probably why he was selling it.

1.Did you check your Accessory belt tension?

2.The condition of the belt itself?

and most important to both 1 and 2 above: Is your tensioner working? (ie is it within range marks stamped on tensioner)

It's the easiest thing to check, that is common to both AC clutch and Alternator.
