96 buick 3800 series II SC. Swaped engine did not discounet the ac compresser to swap engine. Only discouneted the wire to the clutch on the ac compresser. Also getting lean code. Checked all the vacume lines and they all seem to check out good. Also not getting any air flow out of face vents only floor vents. Any Ideas.

As far as the ac goes when the ac hose was not disconnected and moved around it could have been brittle from age and caused it to leak.I would do a pressure test on the ac to see if the charged leak out.
Now for your vent issue and lean code I think there related if they happened at the same time?For the lean issue let the car idle get some carb spray and spray around all the vacuum sources vacuum hoses intake gaskets etc. If the rpms go up down or the engine stumbles or dies you found your vacuum leak.
No vacume leaks on the lines that are connected. And no the ac is charged lines are new car is in almost excellent condition enigne is new rebuilt.
So the ac worked before the engine was replaced as well as the ac vents?Also was there a lean code before the engine swap?So you checked the ac pressure to make sure there was enough pressure in the system to allow the ac compressor to turn on?Also how did ou check for a vacuum on the hoses and what about the intake gasket etc?
Ok let me ask you a different way. Do you know of these cars 96 to 99 having you know. What never mind. I think I already know. More. Than you. Do and this has been a. Waist of. Time
