If you have both "factory" rear heat and rear a/c, you would have both switches on the dash near each other. Both units are on the driver's side. Rear Heat unit, like you said, is behind the driver's seat. Rear A/C is at the back pillar, also driver's side. If you have a unit on the pass. ...

Our problem was - we lost that fine pitch nut off the back side.
Took a couple hardware stores to find one.

Bearings "tinkled" out while idling in front of the drs' office.

Welcome to The Forum.

LOL - well, you know that Alum Diff. Cover is good for 5 HP all day ! Wheels are Very Nice and those center caps - would love to get proper or new or different center cap logos for our '92 Astro. Can you divulge the etsy guy ? Rear sway bar will surely cancel "some" of the rolling breadbox...

Shoot, forgot to ask about that. Is that NAPA only ? All the 'other' places are closer to us by a large margin.
This area has only ADD / confusion parts, O... Really's? and Autojerks/Asszone.

Low miles to boot and "that's a very Large Van, there, isn't it"... ?
Welcome to you from an "Old Astro Owner". Yeah, both of us.

Sweet looking Van on the outside... here's to hoping it's Sweet inside also. Sometimes that wood has seen a 'better day'. Pics are welcome. And like the fellows alluded... factory Vans never had any excessive window tint. Conversions- they generally go out as an "Upfitter" type with usuall...
