Check your switch that runs to your aternator.make sure is grounded .if not get a sand paper and sand it down.also check the switch that plugs in to the alternator.

Why not test the coils? And its handy to have a obd2 scanner saves some guess work

As far as draining the battery, pull the door lock circuit breaker till you can fix the issue. When you drive the vehicle, you can plug it back in. If your sure the door locks are the problem? In my database for body info, if no screws then there is a keeper, with a keeper you use a flat bladed tool under the edge, slide it along till you find a keeper, then release it. I don't like to fool with keepers, I usually break something. Just my opinion.

Make sure the seal from the old filter is not still stuck on the housing. If it is it will leak for sure. I always smear some oil on the new filter seal before putting it on. I also fill the new filter with oil.

Wiper arms are fitted to a tapered and splined shaft and they can become very tight on the shaft even without the problems of poor maintenance - when servicing a vehicle I always loosen the wiper arm retaining nuts and apply a small amount of chain lube and retighten. Subsequent removal becomes a little easier and the chance of snapping a wiper spindle much reduced. These days few wiper arms can be removed without using a small gear puller that is sold by tool outlets for the purpose of removing most wiper arms. Recently a colleague needed to manufacture a "special" for a particular car because mine wouldn't fit. Rear wipers receive no maintenance at all generally and being more exposed to the weather, salt, road dirt, corrosion can be a big factor when removing the arm from the spindle. This is especially so when the rear wiper arm is plastic with a moulded-in ally hub. I have in the past had to resort to carefully cutting and grinding away the arm in order not to risk the spindle or the glass. I suggest you try a wiper arm puller and a little gentle heat and if that doesn't seem to be working then cutting, grinding or drilling would be the best solution, after protecting the glass with lots of forgiving material...

run a check on the start switch possible bad connection for ignition when in the start position

I had a Camaro that did the same thing. Mine was a bad security module in the steering column. It reads the chip in the key. It looks for the chip just after the engine starts.

It may be available at the GM owners site.

it might be your TV cable check that first before you spend all that money on the tranny, if your not fimilair with trannys the cable on the driver side of the tranny is what shifts the tranny itself i would have some one in the van while started and on the brake then you or someone else go under the van and shift it your self which would be 3 clicks from park

the wiper motor seems to be defective, test that first

heat sensor for radiator fan switch, thermistat,water pump? Does hot air blow when moving? does car over heat when sitting idling for over 10 minutes. If so check fan first, then water pump. last cause thermisat

Could be the fuel pump as they use the fuel as a lubricant. When run dry this can cause wear to the impeller of the pump. I would check the fuel pressure in the fuel rail.

It might be your fuel pump not getting fuel to throttle body. Disconnect fuel line to throttle housing get someone to turn car over and see if fuel is getting pumped up. If not the pump could be faulty or fuel filter blocked. Also check to see if you car has a fuel cut of reset button it could just need a reset.

i would check out the positive battery cable that runs to the starter, also , check all of the wires that are at the starter , to make sure that they are not loose, torn, burnt, ot frayed.

Sounds like the accelerator linkage or kick down band of the transmission need adjustment.

I would say to 1st check for any blown fuses. Chance are, there's only one that powers all the listed non-functioning lights. Hope this helps.
