I've noticed recently that if I have my heaters on, say 25deg, with windows closed, when I turn right, the heaters get cool very quickly, but then return to normal.

Same as when I turn left, but then that goes a little hotter, then back to normal.

Is something wrong with my car?

Sounds like the heated fluid is rushing in and out of your heater core when turn. Could be that your heater core is not being fully pressurized.

What???? That's nuts I've never heard of that before. Could be a heater core issue. They run off of engine coolant and while I don't have an exact idea of how they work, they are under the same pressurized conditions as the rest of the system when you have the heat on and it could be an issue with the system keeping hot fluid running through the core. I assume there is some sort of valve that regulates coolant flow. That could be faulty.
