Mysterios vacuum in the cab.. Anyone know what it is?
Today i pulled the ac in the cab to check on things and the next drive i heard hissing. Took it down and found these bad boys sticking out and hissing:
Shortly after investigating where they could possibly plug into i found this hanging on a single screw half ay undone:
They are located right below the heater controls and just curious what they are for and how do i assemble properly. Definitely clear that the plastic piece hooks up to the hose but is there something the plastic piece should fit onto?
No need i see what u mean seems like when i move the vent control a little 'trigger' may push the switch in or let it all out. Hmm gotta find another screw now lol. Doesn't appear like its making real good contact ...
Eh nevermind i figured it out..still don't know what its for.. Guessing it changes the vac if the gates are open in certain position? Maybe cause it to rev up a little ?,Lol don't know but thanks for the help got it all put together. Apparently only 2 tubes and the third one is left open.
looks like something I get to do this summer because right now, all I get is hot air and its not a good thing in SW FL in the summer....
Bet ur gate's prolly not opening properly take the heater out clean it, reseal it rehook the control wires and u'd be all set. did that in feb due to leaking heater core but did not deal with the controls and should have as u can see
Maybe it comes on certain years? Check out the link i posted earlier might be more info there. Maybe its been capped off at the source? Comes through a hole through the firewall above the ac drain in the center somewhere.. Should be a green one and a black one but i think they go through diff holes on the fwall.
