ED.. there are 6 phillips heads screws that hold the glove box interior in..and a bulb-socket.remove the 6 screws with a short phillips head screwdriver..two top front, two bottom front and one each side..remove lamp and wiggle remove the socket toward the cabin interior..then pull the glove box interior liner out..No need to fiddle with latch or hinges on box ..
Once you get the glove box liner out..look back behind atop the ductwork and you will see the bypass vac-solenoid mechanism.
.The control cable on the bypass is coming from the hvac blower climate control console apparatus and is attached to THAT bypass..
The cable does several things..IT'S the mech.temp selector connection from the hvac console unit..and ALSO closes/opens the vac lines that lead to the heater hose underhood vac on off switch solenoid to shut off hot water from heater line and open defroster vent, A/C vent etc. LOOK AT THAT BYPASS switch and operate the temp control lever and SEE IF the cable is adjusted properly to CLOSE it and shut off heated water and open vac to vents..
IF it isn't adjusted properly.you need to remove the pass side console cover and use the turnbuckle on the temp control cable to get the adjustment right..
IS YOUR BLOWER WORKING?
IF it is do the above checkout BEFORE YOU REPLACE THE UNDER Console vac connections..jim
