HI,
Ok, you dont remove the dash or upper dash pad for this job. You remove the lower trim panels underneath the left and right side of the dash, remove the center console if equipped, then pull the front carpet back and remove the air ducts going to the back. Then you remove the heater core housing and separate to remove the heater core
It is along the belt route. It is a 3" diameter pulley about mid engine .It is on a lever about 4" long has a big bolt head and the lever has about 2" of clearance to move back and forth. You release it by turning the counterclockwise.

the p003# codes refer to the heated oxygen sensor in the exhaust pipe before the cat converter
code p 0443 refers to EVAP system and the p 0201# refer to injectors
all have the ECM as a possible cause and as the ECM is the engine management controller then it would be logical that the problem would be in that unit
Substitute it with a known good unit to check
The p 0443 code may be a clue as well because if the EVAP system is not venting the tank , the pump will not be able to pump fuel and the pressure will be below that required to run the engine . That would possibly account also for all of the injector codes
I suggest that you try the ECM fix first and go from there n
Simple, the best way to do this is to pay a mechanic to do it!!
To do it yourself you will need to release the two front, upper engine mounts and roll the engine forward.
You might need use a ratchet strap anchored to the lift hoop on top of the engine and a fixed anchor point in front of the car **that cannot move**. A good example would be the cross brace bar on a 'drive on' inspection ramp.
**DON'T use anything other than the correct anchor points for your own safety!!**
**Roll it forward NO MORE THAN 6 INCHES!**
More will over stretch pipes, wires and over stress the other engine mounts.
After that it is a case of wrestling around behind the engine until you get the plugs out.
As I said pay a good mechanic to do it!
This thermostat is for ls4, if that isn't what you have, let us know. in the picture, 305 is the thermostat. I realize the text is a little small, hope you can read it.
Wiper/Washer System Operation
The body control module (BCM) is part of the windshield wiper motor system and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper intermittent operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The intermittent interval is controlled through a series of resistors within the wiper / washer switch. During intermittent wiper operation the windshield wiper switch low signal circuit is at the same circuit used for LOW operation.
Do you know what a BCM is ? There are DTC'S - diagnostic trouble codes that can set .
DTC B3873
DTC B3874 (V8)
DTC B3874 (V6)
DTC B3875 (V8)
DTC B3875 (V6)
DTC B3922
You said
aboout every 1.5 months) it doesn't start and the battery is drained..????
Do you drive the vehicle every day ? Any charging system messages on the DIC - dirver info. center . After sitting over nignt it won't start ? Or it cranks but doesn't start an you drain the battery ? If the vehicle had a parasitic drain on the electrical circuit it would drain the battery after sitting over night , not every 1.5 months .
GM vehicles have instrument cluster problems that drain the battery , usually after sitting a couple of days , not after a month an a half .
Horn beeping an wipres / washers coming on are BCM problems , Grounds , faulty input signals to the BCM ect.... An these problems can be hard to diagnose with them now happening . aren't electronics great ! Watch this video !

probably-- to program a fob key correctly you should have the car and the key hooked up to a computer so that the immobiliser can be programmed to the key
best done at a service dealer or qualified locksmith
