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.
