After having some problem with my losing my coolant. We flushed it out for blockage..now that's fine and now cold air blows otu of my heating system, why?
I have the same problem. My problem started three years ago when I flushed my system. I have wondered if my problem is not possibly a air lock in the coolent system. Heater will blow out warm air at first, but cools off quickly. Car does not over heat and runs at normal temp.

I had heat this morning than tonight i have cold air blowing out of the heater I had heat this morning than tonight i have cold air blowing out of the heater
I have a the same problem my car gets up to proper temp and I still blows cold air then it drops in temp and go back to cold and won't heat back upI have a the same problem my car gets up to proper temp and I still blows cold air then it drops in temp and go back to cold and won't heat back up

Is the temp.control twist switch for hot/cold, a cable or vaccume activated? Is the temp.control twist switch for hot/cold, a cable or vaccume activated?
My Saturn Vue 2002 blows cold air. I Just purchased it and the seller either did not know or inform me of the issue. The seller has installed a new engine recently[could that be an issue?] There was no colant in the rad, I just filled the bottle but still blowing cold air. Vue is at the mechanic who in unable to understand and fix the issue. Any would be highly appreicated. Thanks, Ibrahim My Saturn Vue 2002 blows cold air.

The water in the radiator must be hot. The hot water must flow through the heater hose to and through the heater core and back to the cooling system. Blockage in the hoses or an inoperative valve will prevent the heating. You might try loosening the return hose to verify that the water is flowing into the heater core and back out. Try this before everything gets too hot or disconnect the input and output hoses and blow compressed air through the system to be sure there are no obstructions. All switches and levers must be set to heat, and all valves open to permit hot water flow. Good luck. Hope this helps a little.
You probably have an air bubble and therefore doesn't have enough anti freeze in the system. Carefully remove the radiator cap when the engine is running and verify it and/or notice the hot/cold marking on the overflow tank. The system needs to be full to heat.
Have the cooling system pressure tested ! 3.1 l engine These engines had intake gasket problems , have the radiator cap tested as well . Bad radiator cap will allow coolant lose . Does the oil cap have whitish or dirty color foam on inside ? Coolant leak into the oil .
check coolant level first. possible bad thermostat, blockage, heater core is bad. check to see if a hose going into heater core is hot, if the hose is hot and the other is cold you have a blockage in heater core. if so, sometimes you can remove the hose from heater core and flush it out with a garden hose. if above fails, flush whole system.
If the temp gauge is hot and cold air is blowing in the passenger compartment, then I would say there would be a blockage or series of blockages in the cooling system. Flush it out and refill with new antifreeze/coolant mixed at 50/50 water to coolant concentration.
Check the codes to see what else may be wrong with the engine.
just because the gauge seems normal doesnt mean the thermostat is good, its 5 years old,and may be opening to soon, i would start by having the t-stat replaced and while thats being done have the cooling system flushed including a flush off the heatercore. i ve worked on a couple of these vans with heating problems, most were low on coolant due to a slow waterpup leak, the others with half plugged heatercores, due to the lack of coolant flushes. hope this helps.
it sounds like the heater core is clogged bad if u know someone with a air compressor put a air nossel on it that you pull the trigger to blos air in to the heater core after you take the lines off i had to do this before on a jeep cherokee it did the job
sounds like you may have an air bubble trapped. Try loosening the radiator cap & running the engine at 1500 rpms till the thermstat opens & see if you can "burp" the air out. You may lose a little coolant this way. shut off car & recheck coolant in radiator and reservoir bottle. Just because reservoir is full, doesn't mean radiator is full.
Your thermostat is stuck open - if you replace that, you'll be fine (may as well have the coolant flushed as well, since you'll lose a decent amount of it when the thermostat is changed).
