Newbie with bad Ac

[ard]

Ima gonna guess your electronics bay has been filling up with water on a regular basis, ruining multiple modules causing buss failures.

Any evidence of this? (other than the water damage in the picture above_)

12.37v on the battery is NOT good enough. That means it's only at about a 70% charge. If you've driven long enough to charge it up fully after sitting for a while, (as you mentioned you did in your first post,) you need a new battery. If this is its full state of charge, that means its not holding a charge and it's shot.

The previous comment about the battery being original from 2009 was obviously sarcastic; these cars absolutely eat batteries. A 4 year old battery is already well beyond its life expectancy.

Don't forget to code your new battery. Don't waste your time chasing faults until you get a fresh battery; these cars are known to have all sorts of mysterious issues crop up when the battery starts to go.

Once the car has its new battery installed, clear all the faults and then see what comes back, and what doesn't work.

I would also look carefully for any other signs of water damage in the trunk and electronics areas. Look in the compartments on both sides, and also completely check the spare tire well, (or where the 3rd row seat goes). Since you're in a pretty arid country, it's unusual to see water damage, but it does not have to be caused by rain or flood. It could be a grocery spill in the trunk area, or a leaky ice chest that was being carried.

So, thanks for help so far guys here’s a quick update - went to another garage who filled ac system with gas, apparently it wasn’t full. A/c still doesn’t work, pulley wheel with belt is rotating, clutch plate is free and turns by hand but doesn’t engage when ac selected. Guessing replace compressor.

When they connected computer to car it gave no fault for rear camera circuit although it did say steering angle sensor fault , when in reverse I get GPS map where camera image should be plus reverse parking tone from sensors.

Skyline just seen your post after updating mine, will go see about a battery and update shortly, thanks.

If you have magnetic clutch. You might getaway by changing the clutch. Just make sure no issue from wiring side.

Almost forgot, I did my compressor replacement at nbk Bosch on st2 industrial. They can do preliminary check as well to confirm the issue.

Hope it helps
