No---- not on any OBD2 System (1996 thru 2013)A code reader is $60 & up ---everyone needs one

open the hood look on the top of the light there will be two pins look like allan keys turn and pull

The fuse you are looking for is in the fuse panel inside the vehicle under the dash on the left side of the steering wheel. Below is a diagram of the fuse layout. I have marked the fuse you need to pull for the horn until you can get the peoblem you are having repaired. Hope this helps......

Have you checked out the fuses to see if one is blown?

Great, fixed

loosen bolts on post(if side mounted posts remove bolts all the way) remove negative line then remove positive. There will be a bolt at the bottom side of battery that holds a plastic lip down so the battery cant move around. Remove that bolt and plastic piece. You will need a socket wrench and a 6" extension, you can probably get to it using a open/box end wrench but it would probably be a heck of a job. Thats it just install new battery in reverse order. Hope I could help out.

I am sorry that you have a poor performance vehicle, but in reality the ac will work well only if the compressor is in good shape. Unfortunately if the fault points to the compressor there is no other way out than to change or service with guarantee.
Please make sure that you have good gas pressure, When the car is idling how much is the cooling? When on motion you have the best cooling due to many reasons particularily the cooling to the condenser with the air flow,clean filter. You can get the cooling coils cleaned well, use forced air jet after removal of the dash, clean also the condenser with a good jet of water spray.Hope this improves,if by any chance there was a filter clogged in the dash blower unit.Hope this helps? Good day

Look up the sensor at autozone or look up where the componets are located for your particular vehicle there.
