Had my 89 converted to r134 4-5 years ago and still seems to be cooling OK, but when I go the diagnostic screen for climate system and press OK for each check selection, I get "very low refrigerant", "compressor overheating" etc. Last summer I got 1 of the r134 fill kits and the gage indicated low but I could'nt seem to get the system to accept any refrig. Any ideas or take to professional? Could it be that the diagnotic msgs are history and not a current problem? Thanks

When I go to the error codes by using the climate screen then touch off and warm button,
I get "NO ECM CODES" AND THEN A B552 HISTORY CODE.
