quick Q guys,

heater is blowing cold, car is running as i would expect temp wise

so i stripped the glovebox out to check servo operation etc

now the wee red servo is turning fine but isnt connected to anything?
what should it be connected to?

should it be connected to the blue linkage part above?

this one

what does this do? and should it move freely mines is solid for some reason and appears to be wedged in place

thoughts please guys, its rather chilly up here in scotland atm
