Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Default Connector Help

First time posting please go easy on me -
I hope I do this right, I definitely don’t want to be publicly shamed

I'm sure this is a simple question for most to answer - what does this connector plug into?
2005 Hummer H2
Originates from main harness, piggy tails off and is mounted to back and around the right side of engine (the side with the air intake system) , another piggy tail off from this which connects up into some module - and then this continues about another foot or foot and a half to connect into????
AC compressor clutch?
could this unplugged little guy be the reason my compressor doesn’t turn on??
thank you so very much

looks like it might be an AC pressure switch harness plug see if one is disconnected.

sorry for delayed response- so I’m not sure but I found where it plugged in - I shoulda trusted my gut a week ago - but I still am not sure what it’s called - it plugs into the condenser

welp I thought that would fix my AC but it didn’t. It blows. But seems the compressor won’t switch on - no cold coming out.
it worked fine until I had to have a new radiator put in - the very next day - no cold air.

take it back to the people who did the radiator. Condensor had to come out to do it. They either didn't seal it up right or forgot to replace the refrigerant. could just be a bad o ring.

that pressure switch looks oily. maybe it is leaking R134 internally.

Possibly but it looks like undercoating/road grime. if you look closely its all over everything.

Try a can of whoop-*** on the connector/switch contacts!
