Hi. My trusty Camry started popping up the batt symbol on the dash last night. It was flickering on and off unless I was on the freeway doing 100kmh where it would stay off. Once the rpm dropped below 2,000 and the speed to 80kmh, it started flickering on and off again. I noticed my drivers power window didn't operate at one smooth speed as normal and my headlights sometimes dimmed for a second and then back to normal strength whilst driving. I suspect my alternator is failing. I can't find my meter to check the voltage and a new alternator is fairly expensive, so I'm wondering if there are other ways of deducing that the fault is the battery or the alternator. Anyone able to supply other methods of deduction?

I have an AC problem where the AC, which blows very chill when it runs, like to turn itself off randomly. The AC light is still lit up as though it's on but it stops blowing chilled air. If I press the AC button off then on again, it starts blowing chill air again. I took it to get the gas checked and they said only very little was missing and they only put in 25 grams worth. I had them run a diagnostic but it only came up with B1424/21 which I later realised was of no use as the diagnostic was performed inside a garage where the sensor can't see sunlight. I'm running out of ideas.

Hi. I have recently become a Camry owner and am looking to fix a few things with my car. Hopefully there are knowledgeable people here.
