After a few attempts and various aricon places i still have yet to sort my air con working on omega
From another post ive gather the following list so things to check and do...
In order of common failure.
Condenser (replaced 18month ago)
Hp/LP valves, HP valve gums up needs cleaning with carb cleaner,,
LP fit a new core, (fitted new one 18months ago)
Pipe under battery box along chassis rail.
Connecting block were dryer is bolted to condenser, leaks.
Compressor seals, and seals were pipes join.(new seals and new drier fitted last week)
Pressure sensors, just stop working.
Expansion valve, up behind dash/glove box.
Evaporator,, very rare to go, whole dash out to replace.
Also check electric plug on bottom of compressor, for broken wire. (Checked and actually swapped for another compressor i knew was good and filled with pag oil before refit)
So as of now it has a new comprsssor new dowdy seals.
New rad
New drier new seals
New valve core
Vaccumed.... held
Regassed
Freezing cold was shocking cold.
48hrs later clutch not engaging.
What would people say is the way forward. Swap a sensor. Or try swapping pipework etc.
