Q: hey all ! i replaced my condensor about a month ago and recharged the system w/a freon and oil combo set with the single gauge setup. all was fine and cold enough then 2 days ago i fired up the truck and the unit was not blowing cold air just cool so i grabbed the single gauge and tested the low side and it read the same as after i initially refilled system. the clutch kicks in intermittently for about 4 seconds and shuts off for about 4 seconds quite consistently. seems like the low on freon symptom. i tried to put a little more freon in but noticed that it didnt seem to help the on then off syndrome. i did not overfill at this point the gauge still being in the blue. is there a solenoid or switch to check or replace for this condition it is hot as hell out here. i dont want to get ripped off by some shop as i was hoping to remedy this and sell this great little truck with 200k miles for a new yellow hemi slt while the incentives are on. any suggestions thanks julio well with out a proper set of gauges not the one gage check method filling as per manufacturer instructions checking pressure chart based on ambient temperature checking the super heat temp a proper leak test properly evacuated the system because all the refrigerant was gone or had air entrainment more than likely not having been trained in automotive hvac or licensed as per the epa you have screwed the pooch and you are lucky you have not blown your compressor or yourself any one of the above is your problem. the compressor cycling it is low on refrigerant leak in system a vacuum held on the system would of found it. if you did not pump down the system it is full of air you cannot evaporate air. -- coasty remove the spooge to reply what about a high pressure cut out switch blockage in the filter or expansion valve causing high head pressure and system possibly overfilled causing low side to read ok hard to tell without a proper set of gauges. just a thought. chris the system has a captube not an expansion valve to control the refrigerant and does not use a hp switch. high head pressure is caused by too much heat from and not enough cooling from the condensing coil thats the one by the radiator. -- coasty remove the spooge to reply .

i think you nailed it she found the handle but it wasnt working must have broke thanks for the reply. billy the gm 3rd door has its own handle on the door jam itself just like the dodge products do. now if this handle isnt working i belive they had problems with either the rod or the handle. ive got some friends that owned these s10/15 trucks and both had door handle trouble with their trucks. hope this is some help. hey guys i cant find a gmc group and besides i know dodge people are smarter anyway so i am sure someone can answer a silly question for me. my father passed away a couple of months ago and now my mom is selling his 2002 sonoma extended cab. from what i have read the third door was standard for all extended cabs in 2002. my mom says it either does not have one or will not open; she read about it in the owners manual and still can not get it to open. since you have to open the drivers side door to get the 3rd door open i would think there would not be a separate lock or a child-protection lock for the 3rd door am i wrong i dont think my mother is a total idiot and can normally manage to open doors so im wondering if there is something simple we are overlooking. does the drivers side door have to be opened all the way before the 3rd door unlatches they call the third-door a clamshell-style if that is any help. thanks billy .

bingo! no difference in an auto ac or residential ac theory is the same the only difference it is more compact. when you draw a 500 micron vacuum and hold it you do not need dyes to check for leaks. i use a ue2000 ultrasonic leak detector it will find any and all leaks and i mean all. dyes in systems are old school i use to use them but technology has taken over. it took me less than 30 seconds to find a leak in a 50 foot x 50 foot refrigeration coil. those cheep leak detectors are garbage the one i have costs over $1800.00 you get what you pay for. -- coasty remove the spooge to reply i dont know much about auto ac but with residential ac you need to pump the system down after a change out like youve described. you need to remove the air in the system as well as the moisture. a starting point would be to evacuate the system. make sure there arent any leaks and weigh a charge in with dye to detect possible current or future leaks. on tue 26 jul 2005 182956 -0400 julio nospamhere@home.net wrote hey all ! i replaced my condensor about a month ago and recharged the system w/a freon and oil combo set with the single gauge setup. all was fine and cold enough then 2 days ago i fired up the truck and the unit was not blowing cold air just cool so i grabbed the single gauge and tested the low side and it read the same as after i initially refilled system. the clutch kicks in intermittently for about 4 seconds and shuts off for about 4 seconds quite consistently. seems like the low on freon symptom. i tried to put a little more freon in but noticed that it didnt seem to help the on then off syndrome. i did not overfill at this point the gauge still being in the blue. is there a solenoid or switch to check or replace for this condition it is hot as hell out here. i dont want to get ripped off by some shop as i was hoping to remedy this and sell this great little truck with 200k miles for a new yellow hemi slt while the incentives are on. any suggestions thanks julio .
