A.I.R. Problem with my 2001 Chevy Blazer
v6 Vortec
dash lights = service engine
codes = secondary air injection
work done prior = fuel pump,fuel filter,plugs wires cap
tech = jk
question = what is secondary air injection. Why does my truck have it.
JK
Secondary Air Injection is an emissions system that pumps air into the exhaust system
at the proper time to help the catalytic converter function more efficiently. A common
failure on that truck is that the pump has sucked up water/snow/ice and has failed.
This will also blow the fuse(s). The fusees are in a little fuse block stuck down between
the fender and the battery. A black cover over the block, a little hard to see. First
check those fuses, i would you will find a blown fuse. If so, you will have to replace the
A.I.R. Pump. There is also a service bulletin for this problem. It involves installing new
pump, and hose assembly to prevent water from being sucked into it

My customer has code p0016 on trailblazer, 4.2 inline 6 cyl
How much to repair oil, coolant leak on 2000 malibu v6
A few other Chevy questions.
2003 Chevy Trailblazer
4.2L inline 6
Battery replacement.
Work done to repair = I tried pulling the HVACB and HVAC1 fuses. Left
for a minute and started the engine left for 2 minutes. Turned off
engine. Turned it back on and tried to see if it would work and it
didn't.
Tech = JK,
question = Dash vents will not work. Manual system.
JK:
I would disconnect the negative battery cable for 10 minutes, then do the procedure you
have tried again. If that does not help, you may have a problem in the a/c control head.
Replacing battery can sometimes do bad things to electronics, especially if not done
properly.
Re-learning the door positions can also be done with the dealer scanner. This re-home is
better than just removing power from the system. And, you may end up there anyway to
have the system properly diagnosed
