inconsistent heat

This 01 X308 is new to me as a driver, so I'm discovering it one new thought at a time. When I have the heat on, blower reasonably high, I can feel genuine heat from the dash vents, but it randomly goes cold rather suddenly, then cn be warm again minutes later. Air pocket in the system? I thought I remembered some discussion of a "burping" procedure, but it's been a few years since I worked on a 308, and I'm not doing any good with a thread search.

Check that the auxiliary heater pump is functioning. They can get to be intermittent when they're going out. I haven't yet had to change mine, but I've seen lots of threads on it so its apparently pretty common problem as these cars age. Unlikely an air bubble unless you just recently drained and refilled the system.

Cooling system hasn't been touched, to my knowledge, so the aux. pump is beginning to be the likely suspect. BTW, I too used to have better luck with searches. I didn't notice the coincidence with the upgrade in how everything looks and behaves, but it all makes sense now. I just thought senility was advancing faster than I was admitting.

The OP never replied back but there’s knowledge in there that I would look into doing such as flushing the heater core.
