You have a failed transmission is my guess. Have a shop confirm this. The cost to rebuild the transmission is really high, so make sure you think the car is worth the cost to fix it.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

It is located on the side of the transmission. See picture below there are two types, one has a short wiring harness and one is just the switch below.

1) please see the diagram and proceed with logic sense for troubleshooting.God bless you

Check brake light switch at brake pedal.

For some reason the brake warning light and battery light are connected, so either system could be having problems. The battery warning light could mean the battery is not being charged, and the brake warning light could mean you are low on brake fluid.I would start with the check engine light and see what the codes are.

I had a 90 Camry.First check to see if the circuit breaker is not damaged (you will find this info in a Chilton Auto Repair Manual for your car that can be purchased at an Auto Zone type store). If damaged, then replace it.If this is not the problem, check the electrical cables that connect to the fan (with the car off). There might be rust inside of the connectors. If so, try to remove the rust with some light sanding and lubricate with WD-40). After connecting them, try to cover both sides of the connector with electrical tape.
