My memory is Stratus has a txv with scroll compressor which has a temperature protection switch (TPS) less than 1 pound refrigerant charge is dubious txv systems are typically slow to equalize 1)TPS will cycle compressor clutch with low charge and high side will be abnormally low while low side will...

HI GM Tech Yours is nominated for post of the month! Pretty good advice to look through the resistor mounting opening. Reminds me of the air flow problem in a pick up I fixed. Turns out the dove hunter/owner threw his doves on the passenger floorboard and the dove feathers were sucked into the evapo...

1) New charging valves typically have a light oil film which aids in sealing. When servicing any elastomer in a A/C system, best practice is to apply lube 2) Refrigerant flow through the charging valve washes off all oil from the sealing surfaces 3) OEM charging is into the high side charging valve ...

The OEM evaporator was a energy waster because it always draws in approx 30% outside hot humid air for cigar smokers pleasure, therefore a add on underdash evap should be matched with a smaller compressor displacement or lower drive ratio. OEMs never use variable compressors with a standard txv beca...

MARK IV had 3 basic hang on evaporators with metal diecast bezels chromed and all used TXV internally equalized: 1)Allegro with approx. 18,500 BTU per IMACA test 2) Monitor with 16000 BTU 3) Escort with 13500 BTU The Vintage Mark IV is a hybrid between the Monitor and the Escort but basically Escort...

Among the most compact evaporators are the european OEM rear seat A/Cs mounted under the seat (pugeot) or in the console (VW Jetta early euro version) The Kysor heat/cool coil you refrerence is more than 5" (maybe 8" overall) and is probably less than 6000 BTU for sleeper cab An evaporator...
