Are you saying the system is loosing freon overnight, or its an electrical problem ?

many thing can be. I recommend to pass the RGBII/computer for better diagnostic, do not waste your time+money. The electronic tech in vehicles is sophisticated. Maybe the BCM is faulty. By that reason you must go to the repair shop. The alternator inside the rectifier can be faulty, and need replace, or windin stator+rotor can be in short and need replace.God bless you

Hi,I am going to try and help you.This could be a problem in the ac system not allowing the ac system to operate.This could be freon loss,But needs to be checked out by a ac mechanic to tell exactly what is causing the problem.The ac may have to be reset,if this is the case.If I can be anymore helpful,please feel free to notify [email protected].

The way you normally test for a drain is to use a test light in series with one of the battery cables. The computer will draw up to a half amp at times to provide power for memory. You pull each fuse and disconnect each major circuit until the test light goes off.

all the speakers and chimes stopped working.

You may want to have your catallitic converter checked

if this is an automatic trans, check fluid level, it takes more fluid in reverse

I see you asking this question many times & othersmaking suggestionsI think you will need to go look at & take pictures &make notes,etc, of another similar vehicle, as diagramsof brake tubing have always been near no existant

The master cyl. has two resivors in it the large one is for the front brakes and the small one for the rears. Follow the lines coming from the front wheels to the block and the line from the large should go there. But it seems to me that the line had different size fittings so they could not get crossed up??

replace your winshield wiper switch

from front, back the pan or the overflow tube up top...which spot...repost please...

Sounds like your piston rings are bad causing excessive blow-by ...meaning your power is going around your rings and building massive crank pressure and using your dip stick housing as if it were a pressure relief valve ...motor needs to be rebuilt by an automotive machinist.

relearn of key less entry is done by crank engine slightly, leave key on until theft light quits flashing. turn key off then try to start. if no start and light is still flashing, anti theft sensor in key tumbler or body module fault..

Did you not test the battery first?You don't jump a dead battery,you charge it,and then have it tested

Go to a reputable auto alarm installation shop and have their best man check your wiring harness. It sounds to me that someone installed an alarm system on your truck in the past and hacked into the OBD II system ( the computer controller for your engine)Just a hunch but my gut feelings are seldom wrong LOLYours Truly,TarsTarkas of Evony na30
