Tsb bulletins 2000 chevy astro vanvan lurches when making low speed turns

Christy, make sure van is all the way up in park, grasp steering wheel and (wiggle) turn back and forth sharply while trying to get key out.
If no success call a locksmith.

Just type in on pc, TSB service bulletins for 06 chevy HHR. it should come up for you. when the page comes up, click on the 4th link down. good-day!

Have you checked your freon level? The compressor will not engauge when the R134 level is too low .More than likely you need to recharge the system after 14 yrs you may have a small seal leak. Try picking up a recharge kit with a gauge attachment. This has worked well for me on my 3 Astros I currently own. Othwise the fuse box is on the drivers side left of the steering column.

2 fuses to check, Kevin: in the instrument panel fuse block, 20 amp fuse #12, Htr-A/C. In the under hood fuse block, Frt HVAC fuse, 30 amp.

The new resistor you put in, was it called a "Blower Motor Resistor and Relay Pack" ? It appears there is a relay there with the resistor, but appears to only be used with htr on high speed. However the low speed wiring is also routed through this relay. If it was the Pack you put in, guess that is not an issue.
In the Heater and A/C Control Module is the blower switch. The power in to the control module is a brown wire (from the #12 fuse in instr. panel). With key on should be hot. It appears the brown wire goes to the mode switch and then to the blower switch. Check for power in, and check continuity of both switches. Or check if blower switch has power to it, then check for continuity in it-it should have continuity in all speeds.
If all is good so far, you need to check if blower motor ground is good.
Here can be found a wiring diagram for your Astro. Look for heater controls under the system called "HVAC". Every wiring diagram and TSB for the Astro (or any make, model) can be found here:

For the 2000 model year there were several TSB ( technical service bulletins) issued concerning brakes on your vehicle. There were no recalls concerning brakes or brake failures however.
You can check the following web site and search information on the tundra recalls and TSB's for more detail.

Good luck.

Sounds like you have a c/v joint beginning to go bad...Could be wrong.... but, I'm not there to test it! Look underneath and see if any c/v boots are torn... that will be your first clue!!

Well there is a rev limiter built into the pcm on your car. It is much lower rpm's in park and neutral. When u hit the rev limit of a particular gear selection, the pcm starts cutting out the injectors(fuel). This is normal. As far as the jerky feeling, the only thing I know of is a service bulletin that may apply to your car. It involves a revised torque converter for the transmission. It would only apply if your feeling this at speeds of approx 35 mph or higher when the torque converter lockup engages after a shift. Ask your dealer about a possible tsb for this if you think this may sound like your problem or search for tsb's(technical service bulletin's) yourself on the internet.
