cordoba, managed to figure it all out!....I have the wrong mirror. Turns out I have heated mirrors and I didnt even know!......put my hands on them with the rear window demister on and they went warm.
Part he gave me was for non heated......also realised that the spades just pull off and I will re-attach onto the new mirrow when I get it tomorrow. So it will be a 1 sec job and alot easier than I thought.
Only downside was I have to pay £25 for a heated one instead of £17 for a non heated.
Cheers for your
help
