Just bought a Freelander
 

Hi guys just bought a freelander.
shes just out of mot but nice tidy car 2002.
1.8 petrol (yes i really wanted diesel).
o got her cheaply as 3 amigos on and also needs tailgate handle replacing.
im a reasonable diy mechanic with guidance.
so guys ....
q/ where do i start in trouble shooting the amigos?
can any of you recomend a place for spare parts such as the tailgate handle.
i understand the amigos are a source of frustration.
it would help if someone could give a checklist of what to check,how and maybe a sort of batting order of what you check first.
many thanks guys and im glad to join the club(i think lol)
