Take it back to Toyota you'll having gas pedal issues...

If you are using the factory headunit, it is most likely an amplifier problem( check your fuses). Bad news: You have to have the factory headunit and amplifier for either to work. Good news: There is a lot of options for aftermarket setups. You would have to do a complete rewiring. Check out www.6thave.com

Theres most likely a bad wiring connection between the speakers and the head unit. The amplifier could be bad, but most head units have their own small built in amplifiers so if you'r getting no sound at all..check the wiring.

Sounds like the heater core may have sprung a leak of coolant--although, there should be the sweet smell of antifreeze. If the heater hoses are original, they may be the cause of the leak due to rotted ends. In any case, the heater/air conditioner case will need to be opened, cleaned and repaired. You may need to replace all under-dash vent hoses to get rid of all the smell. Good luck!

You may be having problems with your automatic transmission. Have your vehicle's ECM and TCM checked for the presence of diagnostic information, and proceed diagnosis from there.

for the air cond to work there is another device that is connected to the pulley of the belt driven compressor that is connected to the altenator.When you opt for air cond the pulley should start and if it does not then the a/c will not work.There are many reasons why it does not work but the most common is because there is not enough gas in the system...as a rule any vehicle will lose 10% every year and it is low then it won't work.Hope this gives you an idea.

to reset any malfuntion in memory , disconnect the negative battery terminal few minutes

Its seems tht the vaccum pipe to the brake servo may have snapped or disconnected.
Check tht pipe which you will find it on the servo where the brake mastercylinder if fitted, follow it to the intake manifold..somewhere along the pipe you may find the problem.
Hope this helps!

Hi.

Flush coolant fluid. Disconnect all hoses and wires, marking each wires with a numbered cello stickers. Put the same number in the location where the wire was connected. Same about vacuum lines and hose. You may even take a picture of connections.
Undo the manifold bolts and pull off the manifold
Clean carefully the mating surfaces if you need to replace the gasket.
Do same operations in reverse order to install the mainfold back.


A chilton manual with the full illustrated procedure can be a great help.
