How do I gain access to G200 ground point? - 2002 Pontiac Montana

seems to be a ground circuit . Do you know how to do automotive electrical testing ? specifically voltage drop testing ! There are no grounds in the steering column . The power door locks ground at G - 200 an G-203 G200

Is the air bag light lit ? Clock spring ! do you know what that is . No horn . The battery drain needs to be diagnosed doing parasitic drain testing .

Sounds like you have lose connection , probably a ground wire under the dash . May mean pulling the instrument panel to find it . Ground 200 is ground point for instrument lights ,

Any component that has a ground problem, why not try a redundant ground wire to see if components will work ok? A redundant ground hasn't failed me yet, I suppose it could, but, so far so good.
In my database for ground distribution wiring, I didn't see a g200. I even looked at wiring for engine control diagrams, couldn't find G200.
Is there a component that is having a problem?

My diagram is showing that the ground goes through the instrument cluster not G200. If you unplug connector 2 at the heater control there should be power on the first 4 wires with the key on. The 5th wire is the G200 ground. If there is power plug it back in and see if there is power at the blue with pink wire on connector 1 with the connector plugged in. If there is power there than there is an issue with that wire or in the cluster. it is also possible that the TIPM or the cluster detected a problem with the HVAC and decided to shut it down. You would need a scan tool to see if this is the case.

Have you checked your IOD fuse ? Quick Tip Signs of blown IOD Fuse on Chrysler Dodge Jeep Fiat or Ram...

the following checks need to be made.
All listed components are all share a fuse , and all share the same ground, G200.
Check the fuse/circuit breaker for power on both sides, if OK, follow the harness to connector C214 a 12 pin connector to the right of the glove box opening to see if there is a problem there.
Ground 200 is located on the toe plate at the front edge of the passenger's front door. Check for bad connection there.
If everything is good up to this point you will check The Black/White wire that runs through the main harness under the dash, and splits into several Black/White wires at splice S245, in the main wire harness under the driver side of the dash.

check the g200 ground wire behind the insturment cluster. Im the forman for a chryler dealer I have seen that the ground nut is loose when you disconnect the battery you are reseting the modules.

Not really.

I have had success on various units retrofitting with the Handi Van innards.
