THE "JUMPING" (IF IT'S MINOR) MIGHT BE THE A/C CLUTCH CYCLING OFF AND ON (WHEN IT'S ON, THE COMPRESSOR STARTS TURNING FROM A DEAD STOP)
AS FAR AS CHECKING THE A/C WITH YOUR CHARGE KIT, ME AND YOU BOTH AIN'T A/C GUYS, NOR DO I OWN A SET OF GAUGES, THE BEST-US WAY TO USE A KIT LIKE THAT IS TO SEE SOMEONE WHO KNOWS WHAT THEY ARE DOING USE/ CHECK OUT THE SYSTEM.
IF YOU WILL TAKE THE BRAND NAME OR IT'S ADVERTISED NAME OVER TO "YOU TUBE", IT MIGHT BE POSSIBLE TO SEE A FACTORY REP EXPLAIN IT FULLY, SO THAT YOU KNOW HOW TO USE IT CORRECTLY. (SEE IF IT'S GOT A GOOD CHARGE/ OR NEEDS SOME - DUMPING A FULL CAN IT IT MAY BE TOO MUCH AND MAY HARM THE SYSTEM)
THE ONE I USE IS CALLED "A/C PRO" (IT'S ON YOUR TUBE TOO), I LIKE IT BECAUSE ONCE THE "BEGINNER CAN" IS EXPENDED, I CAN STILL USE THE "TOP ASSEMBLY" WITH THE SMALLER LESS EXPENSIVE CANS. I HAVE A "SPARE CAR" ('95 NEON) THAT IS SELDOM DRIVEN, IT WILL HOLD A CHARGE FOR ABOUT A MONTH, I CAN TOP IT OFF WITH ABOUT 3/4 OF A CAN AND GET ANOTHER MONTH OF COOL. WIFE'S FORD ESCAPE USUALLY NEEDS ONE CAN TO MAKE IT THRU THE SUMMER. AS "CHEAP" AS THE GAUGE IS ON THESE CHARGE KITS, YOU DON'T HAVE TO "MAX OUT" ON THE GAUGES PREFERRED PSI. IN FACT, IF YOU ARE AT THE BOTTOM END OF THE SCALE, VEHICLE RUNNING, A/C AND BLOWER ON MAX, AND YOU ARE GETTING REALLY COOL AIR OUT OF IT, I'D STOP THERE, BETTER SAFE THAN SORRY!
ABOUT THE DOORS, AS I MENTIONED, THEY CAN BE ACTUATED BY SEVERAL DIFFERENT MEANS. HECK, A DOOR CAN JUST BREAK AT IT'S HINGE PINS AND WON'T WORK EVEN IF AN ACTUATOR IS IN PERFECT SHAPE.
MY PAP'S TRUCK WAS JUST AN EXAMPLE OF VACUUM ACTUATED DOORS MOVING POSITION-WISE WITH VACUUM BEING HIGH OR LOW.
YOU MAY HAVE "INTERNAL DOORS" WHICH MAY DIVERT AIR OVER THE HEATER CORE WHEN USING "HEAT", THEN CLOSES THAT OFF, THEN THE AIR FROM THE BLOWER IS NOW DIVERTED THRU THE A/C EVAPORATOR WHEN YOU TURN THE A/C ON.
FORTUNATELY, I DRIVE A '77 CJ-5 AND A '46 WILLYS (NEVER HAD NUTHIN' BUT CJs, SINCE I WAS ALLOWED ON THE ASPHALT IN 1981).
"WILLY" SORTA HAS NO ENVIRONMENTAL CONTROLS EXCEPT FOR MY HOMEMADE HEATER BOX (HEATER CORE AND SQUIRREL CAGE FAN) I PUT IN DURING THE WINTER ALONG W/ THE HARD TOP.
"MR. JEEP" (MY '77 CJ-5) HAS HEAT AND OUTSIDE AIR (VENT). EVERYTHING IS CABLE CONTROLLED.
HEAT IN THE FLOOR OR DEFROST OR A COMBINATION DEPENDING ON HOW FAR I PULL OUT THE DEFROST KNOB.
WHEREAS "HEAT" OR "VENT" (BEFORE IT MAKES IT TO FLOOR OR DEFROST) IS CONTROLLED BY AN "INTERNAL DOOR" (CABLE CONTROLLED)
IN PIC 1) THE LEFT SIDE OF THE DOOR SWINGS UP OR DOWN. "DOWN" TO RUN AIR THRU THE HEATER CORE (WHICH IS ALWAYS HOT ON A CJ) OR "UP" WHICH BYPASSES THE HOT CORE, AND ALLOWS OUTSIDE AIR TO BLOW THRU THE SYSTEM.
JUST SHOWING YOU THE HIDDEN STUFF/ HOW AIR FLOWS THRU "MY SYSTEM". IF MY CABLE BROKE, I COULD MAYBE HAVE NOTHING BUT HEAT, NOTHING BUT AIR, OR A COMBINATION
SOME SYSTEMS CLOSE OFF THE COOLANT FLOW TO THE HEATER CORE WHEN THE A/C IS ON (STILL MAN-MADE, CAN BREAK)
AGAIN TRY DIFFERENT SEARCHES ON YOU TUBE, LIKE YOUR VEHICLE'S INFO AND HVAC, OR A/C, ETC. YOU MIGHT FIND A SIMILAR SITUATION TO YOURS. I'VE SEEN SOME "HEATER TREATER" VIDEOS SPECIFIC TO CERTAIN CARS. I DIDN'T CARE ABOUT THE TREATER PART, BUT THE VIDEO SHOWED ME HOW TO GET TO AN ACTUATOR, AS IT CONTINUED ON TO THE TREATER PART.
I HOPE I'M AIDING YOU JUST A LITTLE BIT
YOUR TURN
