Had to try out the AC hose crimper even though I am out of town at my mom's house this weekend and headed to Colorado in the AM. When I get back into town, will finish fabbing up the hoses, wire up the compressor, vacuum the a/c system and get it charged up. Probably go ahead and use the Sanden 4261 I pulled off the Express last summer even though the Valeo currently bolted to the brackets worked great as well.

Before I left town, I dropped the underhood portion of the HVAC case back into place, with the new evaporator core and blower motor in it and sealed it up well. The only air leak is the condesate drain hole in the box now. Blower motor now receives 13.6 volts at the power and ground terminal with the alternator charging at 13.9 volts at the battery. Between the clean new evaporator core, resealed box, new blower motor and revised wiring the ac vents literally blow twice as much air now. I have not even gotten to the point of pulling the dash to get to and work on the rats nest of conversion wiring that I disconnected. Will be resealing the inside ducting yet which leaks at every connection from the non-existant foam seals that were once there. I did test the heater though, after flushing the old OE core and hooking it up to the L31 heater hose connections in the same manner as a factory L31, the heater started blowing heat quickly from a ~40*F cold start despite the two holes I drilled in the thermostat. After a few minutes of running, the engine reached 180F at which point the dash vents were blowing over 150F, too hot to keep your hands in front of the vents for long. Unlike most newer vehicles, these older GM vehicles can actually operate with the recirculate option selected while using the heater (if the vacuum line is removed off the heater control valve and plugged for winter months) and if the ac system has signifigant enough pressure to activate the cycling switch, the ac system for dehumidifcation. I find it dumb that the newer climate control systems prevent easy use of the recirculation while using the heater. Recirculating air when it is cold with high humidity like in misting rain or fog really helps dry the interior air preventing the windows from fogging. You can crank the vent selector to max ac, temperature to hot, and blow the outer dash vents directly on the side glass as needed to clear them of moisture buildup.

Also tested the lighting after adding the load resistors to the front turn signal circuits. All working as intended, no hyperflashing of the turn signals or hazard lights or any of the weird stuff common with LED conversions. Just putting LED bulbs in it initially without the load resistors, resulted in sidemarkers that would flash for second, then dim out, while the turn signal indicators in the dash would glow. Unlike how dim the lamps were with halogen bulbs, you can actually see the lights like a modern vehicle now.
