Fed up of the all or nothing heater.

Thinking of buying one of these: https://www.holden.c...hes&pCode=78527

If I wired this into the heater power switch would it allowed me to adjust the speed of the blower?

In theory yes but some motors need a minimum voltage to work so they dont run smoothly, I'd not be paying that sort of money though, I suspect you'll end up with a inefficient blower. If it was a fiver try it and see?

A pwm speed controller is what you want. Have a look on eBay, there not expensive. I think the heater motor is rated at about 4A but check this first
