Sounds like it may be the Heater Bypass Valve (HBV) located behind the top of the drivers side of the engine.
Looks like a small plastic starship enterprise, bit fiddly to change if you have big hands.

You're better off going to Vauxhall & buying OEM. It appears there's been a few pattern parts that fail sooner rather than later, & due to where it lives, you don't really want to be changing it twice. If you want a lift in changing it, & fancy a trip round the M60 I could give you a hand.

Should be about £30 quid from Vx.   Not worth bothering with anything else in my view.

BTW I have had 3 Omega's and changed 3 of these things, so its a regular failure point.

Hardest bit for me was getting the wipers off..  ended up buying a heavy duty Sealey puller which worked a treat.
