Q:Hello , my question is ; has anyone ever experienced an internal leak from the original switch , and could it come through the switch ? I have a 1992 Honda Accord and I am losing the AC charge . I noticed the switch and the pipe below it was covered in oil so I cleaned it . I've seen no more oil so I unplugged it and there was oil inside the plug and socket . The switch still works fine . Thanks for any reply .
A:Hi CC, Sorry, without the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. I would suggest that you to take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.
Q:where is this switch located
A:The switch location on each type varies. For further assistance, please provide the year, make, model and engine size of the vehicle in question.
Q:do you have to uncharge system to change this switch
A:No, need to drain the system. This switch unscrews from the accumulator. There is a Schrader valve in the accumulator.
A:The answer to this question varies by vehicle. While it is common, as indicated in the reply by AAP, to have this part screw into a shraeder valve, this is not done on all cars.
Q:what does this switch control and would it cause the compressor not work
A:This switch cycles the AC compressor on and off.
