Door lock question

[RandyM]

Have auto/master lock system. Is the only way to lock driver door from outside with key? I thought it should and used to lock manually with button before closing? Suspect I'm wrong. It locks/stays down when door is closed and all doors lock when I press the button and stay locked but drivers door button pops back up when door is open/unlatched. I've opened up the panel and it seems the latch needs to be engaged to keep the button down.

On the plus side, replaced all heater/A/C universal joints, got the gerbil out of the vent fan but it still chirps, it was burning fuses due to an obstruction, literally saw two fuses in flames; and rolled over 190k miles. Bad news, sunroof pooped out, $2.00 plastic part but it's an afternoon at least. And a four year old smacked a rear marker light and broke it!

Also think I have perpetual richness(smell and 17-18mpg), if it's the AFM that's tired wouldnt the O2 sensor compensate appropriately, or maybe the CTS is shot?

One more thing: threw an adjustable timing light on and found a white? mark but never saw a ball. Maybe a different flywheel?

Thanks, Cheers and happy fall equinox

Yep, that's how they work. You can only lock it with the door closed.

O2 sensor circuit will only do so much. Check fuel pressure too.

M/T? Yep, there's a ball in there. It can be hard to find. You will only see the ball within about a 3 degree range and probably 100-150 RPM too. It's easy to lose, visually.
