hello
i have a 1993 toyota 4x4 3.0L with Automatic trans.

this is my sons truck. he first mentioned that the brake light was coming on sometimes. i figured it was just a switch.

last weekend i helped him change the oil on the truck. after we finished i started it up and noticed the battery, brake & AT oil temp ight all on.

he said up until right then, he had never noticed the other 2 lights.. just the brake light.

this AT oil temp light is on all the time, even when the vehicle has just been started after sitting overnight. i did check the fluid and it is at the correct hot level.

i searched the forum and found a lot of info about the brake & battery light being on all the time and that it is my alternator going out.

is it possible that the AT oil light can also be a symptom of the failing alternator?

thank you

Yes, the AT oil light comes on with a bad alternator. I can about guarantee that the alternator is your problem.

 

great to hear that. thank you very much for the reply.

 

No problem. Most of the time, the alternator brushes are the culprit. You can buy the brushes for a couple of dollars, or you can buy the brushes pre-soldered into the holder for about $15-$20.
