Hi Wayne, it's a 2004 Peterbilt 387. The HVAC is under the hood attached to the firewall. I'm not wanting to break the bar that attaches the two wipers together, needing to know if there's a lock on this or if it just snaps off and also anything else not obvious in removing the HVAC box.

Hi Kerry
Ok, that long arm that attached to the two arms it
is a ball and socket use a screw driver to pry apart
and channel locks to snap together
make sure you disconnect the wires going to it prior to pulling it out
