Do you know what fuse is the park assist fuse for a 2007 Chevy Avalache?

Check the wires behind the fuse box and where those wire go through any metal bulkheads or framework. You do indeed have a dead short. Look for insulation rubbed through. Also work from the lights backwards to the fuse box.

See the awd fuse in under hood fuse box, not only check the fuse, use a test light and check voltage on fuse circuit, key on. There shows to be four park assist sensors at the rear bumper, they have three wire connector, that is ref voltage--ground--signal. You also have a rear park assist module, At the moment, I don't know where that is located? Any applicable trouble codes relating to rear park assist? I have some text explaining the operation, but, not really any troubleshooting sequence.

The Blower motor could be bad. Up under the dash on the passenger side. Probably under a cover of some kind. You can try hitting it (lightly) with your hand.

Well I don't think they come with a spotlight. but if your talking about the fog lights, it should be below the headlight switch or on the headlight switch. Check there and if not then let me know.

The HUGE MAXI FUSE is probably burned... IF I remember correctly, it is a 80 or 100 Amp

First you have to make sure the bulbs are good, if they are check out good, you need to check the fuses and switch.

{: ) If the SERVICE PARK ASSIST message is displayed on the cluster, the on/off button will have no effect. It seems that the repairs was not fully completed. There is still a fault present, and it will give a code. Did they use a scan tool when they replaced the sensors? It's possible the wirings and connectors could have been affected too, or even the module. By the way, have you checked the fuse OBS DET at the IP fuseblock?

your catalyctic converter is simply a pollution filter in your exhaust line, it could possibly maybe be your problem if it is blocked over with carbon just remove it and check for a carbon build up, its rare tho for it to cause the car to sputter
