Hey guys,
Hopefully someone can answer this question.
JUST FYI:
Just did coolant change 60/40 and 195 degree stat last week. Well past due and in hopes to figure out an ongoing heating/cooling issues. Truck never got hot in the winter and never really cools in the summer (unless refrigerant is added). According to my scanner looks like the stat is opening and closing correctly. It gets to temp at 195-197 then opens and temp drops.
Started the truck this morning 51 degrees out. Ran it for 20 minutes with the defrost on The morning condensation/moisture was still on the windshield after 20 minutes except for three softball size spots at the defroster outlets. Looks like it got to about 80 degrees and maxed out at a 100. No big deal the wipers work.
Figured I'd tackle this early. Warmed up the truck (obviously it gets to temp). I open the glovebox and lower the door enough to gain access to the plenum. I have an access point where I cut it so I can inspect the blend door whenever I needed. Figuring that the 22 year actuator finally crapped out I'd take a peek. Blend door is opening and closing with no issues and sealing. Did notice cool temps in there though. Turned the setting to VENT and it got up to 120+.
These heating and cooling issues have been going on for years now. I always have a thermometer in the vent 24/7/365. My passengers care more about the temps more than I do. I drive with the windows open if either worked right anyway.
After seeing it get up to 120 degrees I figured would run through the settings (still 51 degrees out)
MAX/AC - Cool temps in the box, actuator moves, clutch engages
VENT - 120 degrees at vent, actuator moves, clutch disengages
PNL/FLR - 120 degrees at vent, actuator moves, CLUTCH ENGAGES
FLOOR - 120 degrees at vent, actuator moves, clutch disengages
FLR/DEF - 120 degrees at vent, actuator moves, CLUTCH ENGAGES
FLR/DEF - 120 degrees at vent, actuator moves, CLUTCH ENGAGES
Pretty dumb but I'm thinking the settings had to be run through like a tranny, sounds weird to me.
Vent blower tested with a piece of paper and it moves. Defroster blower tested with a piece of paper and it moved away. So no blower issue.
QUESTIONS:
1) Is the A/C clutch supposed to engage in heat settings? ANSWERED (YES)
2) Could something be disconnected (I.E. vacuum line)?
Thanks for any input.
