My air con on the GTD has failed, I've looked for the charge points (high \ low pressure) to check the gas pressure but can't find them anywhere (not near compressor or under the dash). Is there a usual place to locate them?
I have found the leak, the binary (pressure ) switch mounted on the receiver \ dryer has failed. Does anybody know where I can get a replacement dryer & switch?
By the way you were spot on, the service ports are on the compressor.
