Re: Windows lose index and slow hot start
Being you replaced the starter for a problem and then still had problems leads to real issue and I agree
heat changes resistance including to a cell in battery
With engine heat soaked, if a battery charger hooked up, does problem not occur ?
Being problem with clock, I would think would be with the radio controller
Index of windows a issue, BCM controller,
Start issue is tied to both the BCM and PCM so now that is multi controllers
IF load test done after engine bay heat soaks passes then battery can be taken out of the possibles
Next would be grounds, as most controllers command functions by reference to ground so if weak, loose, dirty, etc
ground highly effect controllers.
Check again by BCM under floor hatch, closely look at the Starbus, BCM, etc wiring connectors, see if some mouse has not gotten in there and also where PCM is located that has been chewing on wire looms.
Check main engine to chassis ground, rear of left backside of head to chassis.
There is multi spice packs grounds, look on frame, see multi grounds going to a little box that bolts to chassis
That splice pack comes apart, a bit of bitch doing so but inside are male and female connectors, clean up well
When cold, open door, does the security light on dash flash ?
When hot does it still flash ?
Starting issues sometimes is there is a safety switch on clutch pedal, if out of adjustment or faulty switch causes a crank but no start.
Focus on the BCM connectors, see if any water stains showing
Take inner fender side off on right side to get to PCM, check grounds and wiring and pins of wire looms
You really need a OBD-II scanner, to see if ANY controller is hiding any error codes or U codes which means a controller(s) cannot talk on the Starbus network
