Hi All,

Just a follow up on my original post above where coldair only on one side and normal air on the other side.
I finally started to get warm air on both sides , so i decided to add some refrigerant and the problem was solved instantly. I did not think of that at the beginning because one side was cold. I am assuming that the system was low on refrigerant and was only able to push cold air to one side and not the other. Very strange with LR3's.

Thanks for all the help

That does not actually make any sense, cause that is not how it works. What are the pressure readings?

That is sensor based, never to be considered actual incase a sensor is failing. So physical gauges are always the way to go. Both for proper diagnosing and safety. But assuming all those values are correct your high pressure is wicked low. If your air temp is really 40.5C (over 100 F) your high pressure side should be over 300psi with the low side around 52psi. Also while I am only used to clutch driven AC units, that amperage draw seems incredibly high. Combined with cabin blower and viscous fan you are exceeding well past alternator capacity.
