so i finally got a 300td. it is a 1984 in good condition. the turbo dosent work nor does the kickdown switch. it is slowwww. i have checked the alda line about five times, its clean. i replaced all the filters. no change. i looked at the actual turbo and it spins. i am almost stumped. i played with the alda adjustment but not much(quarter turn no difference). as far as the kickdown switch, i have heard it is tied into the ac wiring somehow? is this true? my ac fan dosent come on even tho the fuse is good. i also replaced the actaul kickdown switch to no avail.

what should i do? any help is appreciated.
