on the backside there is a 7 or 6mm bolt that holds it in. You need to pull off the chrome knob as well. Have you taken the resistor out to make sure that is not burnt and causing the problem?

On the top bolt it is hard to fit something in there to unscrew it, the heater works
But it doesn't blow hard on high or Low

It's been a while since i replace my blower switch but if you remove the unit you'll see the bolt. When I replace mine the other switch circled in red was giving me problems as well with intermittent on off

Can I only replace this part?
