Are you sure it has rear heat? Most only have rear A/C.

Hope this helps

I have 2000 astro van and I'm not getting heat, I changed thermo stat and flushed heater core. Still no heat, whats the next step?


Feel your heater hoses. If both are hot, the core is circulating. If only one is hot-poor or no circulation of the core.
If the heater core is circulating, the temperature blend door may not be working to let blower air pass across the heater core, and into the vents. If vacuum operated, watch the vacuum valves as you move heater controls-you may spot the problem. Check that the vacuum line from the engine to the control switch is working and still connected. If not operated by vacuum, the controls may have cables to the heater case or may be electrically operated. You'll just have to scope it out. Good luck.

Cool air blowing from heater in front and back heaters in 2000 asto van


Have you checked the coolant level? If it is low on coolant, none will circulate through your heater core. Check your reservoir and your radiator (when cold only). If that isn't the problem, check the hoses to the heater core to see if one is hotter than the other. They should both be at least warm, but the inlet hose should be slightly warmer. This is all assuming that your thermostat is good and your van actually gets warm when you're driving it. In the situation your coolant is low, fill it. In the situation your heater core is clogged up, it needs to be replaced. Obviously you'd rather just have to fill the coolant.

Another issue could be in your interior controls and duct work. My Astro doesn't blow on the heater setting at all on the driver's side. Electronics and electrical problems annoy me so I don't bother to fix it. There should be a duct that opens and closes to let in either cool or warm air, or a mixture of both. If that's your problem, I can't offer a solution besides a small heater you can plug in the cigarette lighter.

Chevy astro van heater blowes only cold air


the problem is probably the heater core, it can become clogged with dribris. this stops heat from the engine getting to it and then no heat.

Heater hose, 95 Astro


SOUNDS AS THOUGH THE HEATER CORE IS PLUGGED. TRY BACK FLUSHING IT AGAIN. IF YOU STILL GET NO FLOW IT IS MORE THAN LIKELY PLUGGED AND WILL NEED TO BE REPLACED. THE TUBES ARE VERY SMALL AND PLUG EASILY WITH RUST.
