This valve has a power and ground wire that were in bad shape so I was replacing them.

PN is partially unreadable. What I can read (sort of) is 280141001 (its Bosch). I tried a 9 in front of it but can't find it in PET or manually in a parts manual.

What does it do, what symptoms would it give you when not working and how do you check if it is working?

Thanks

 

That a the ac supplement air valve. Kickes up idle when compressor is engaged. Power is from the compressor clutch wire. Wire it to the jump post. Should click wh en you ad power

 

I was monkeying around with mine...and when I unpluged it just to see how the car would react, it would idle as if the a/c was not working/engaged....

 

So right now my AC compressor assembly is removed. Can I leave this disconnected as well?

 

Yes, it is only to provide additional air to bump up the rpm's a bit for the load that the compresor adds.

 

Jim,
Roger has the parts number for the short wiring harness that goes there. I just ordered one to replace it on my 79.

 

i remade mine.

 

I saw the PN on the wire harness but it look fairly simple, single wires. What did the harness from Roger run?


I was planning to do my own as well as I did not see anything special from a wire or connector perspective.

Thanks all.

 

Correct Harness $21.
I also ordered two for my own cars.
