Multiple mirror problems

[Eddiebassman]

Hi all. So I’ve bought a rover 75 cdti connoisseur. I got it cheap and there are plenty of issues to solve.
One of which is the electric mirrors won’t adjust, won’t fold or heat up.
I’ve replaced the drivers switch pack as I needed one for the osf window as it broke off. But no change.
When switch is selected for each mirror, or the folding button, they do light up so there is power at the switch.
Can anyone suggest something which could cause all these errors?

Ps my heated seats don’t warm up, though the light does illuminate on the switch. I thought this worth mentioning just in case this is somehow related.
