I am assuming you mean heater core, you have to remove the pass rear cargo trim panel and any trim that interlocks to it as well as any connectors then the heater box and hoses from under the vehicle as well as if it has rear ac the ac system needs to be discharged first and those lines removed as well, then remove the box from the vehicle and seperate the case halves and replace the core, the reinstall in the reverse order of removal

SOURCE: I need instructions on replacing driver side rear

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Then you can access the bolts that secure the mirror onto the door

You just have to reach under the shield and grab the boot. They are tricky to get to. But the plugs are kinda hidden. If you are changing the wires, you can just pull on the wire, then use a socket to get the plug out.

Hello Nick.

I just went through the wiring diagram looking for the relation between the two problems you have.
If you can see it in the diagram below it will show you that the wiper motor and the access light both share a common ground circuit. .
And the other wire in common goes between the wiper module and the body control computer liftgate ajar switch sensor wire. This one will prevent the activation of the wiper motor when the hatch is open.

I believe you will need to go through the diagram and test the circuits and find out which of the wires is causing the issue.
Is the ground circuit open, or is one of the latch switches shorted?

A multi meter, some time and patience will repair this if you are comfortable in tracing electrical problems. If you are not too comfortable doing electrical repairs this one may end up with you getting very frustrated...or worse ;)

I hope this helps you towards a good repair.
Happy New Year and thank you for using FixYa.

2003 suburban with rear air, 27K mi, rear ac and heat are fine, but the front air diverter doesnt seem to work. I switch between defrost, face, and floor modes but no changes. I replaced the climate...

If it is a mechanical switch that you turn this system works by vacume it could be the vacume supply hose coming from the intake manifold is either off or broken.

You could also have disconnected it by mistake when you changed the climate control. Good luck

Driver Heated Seat 03 Suburban

The most likely failure point is the driver heated seat elements. They probably have excessive resistance and once they warm up a little they short out the module and it defaults to not working. I would recommend replacing both upper and lower driver seat elements.
