2001 S10 V6 4X4 P/U
Noticed a bubbling noise under the dash for the last two years. More prevalent when accelerating. I figured I had a plugged A/C drain and was hearing condensate slushing around in the housing. I never did find the drain, but my cousin, an S10 owner, said not to worry about it. I noticed this past Summer, it was draining A/C condensate as it should, so I assumed it fixed itself, as I no longer hear the 'sloshing sound'.
Well. Now the heater barely puts out warm air.
One of the two hoses is hot, the other is cold, so it seems I'm not getting flow through the core. I traced both hoses down, looking for a "heater control valve". None found under the hood. The coolent level was down just above the ADD mark when cold. I've added about a pint and it hasn't gone down. I can't say it hasn't been low in the past. I always go to Midas for oil changes, so if they added any coolent and didn't tell me.I'd have no way of knowing.
Anyone have an idea where to start?
have the same problem?
