300DT Cruise

Trying to diagnose a dead cc. Replaced the column switch because the stalk was broken off, pulled the cc module and resoldiered to connections. She's still dead. Is there something else obvious I
should ck? Is there a way to power up the actuator to see if it is functioning? Any insights appreciated. Thanks

is there vacuum getting to the canister?
just apply 12v to the electrical connection, if the engine revs instantly start going up very fast, you know its working and that's not the problem. also, having the incorrect wattage brake bulbs is known to permanently destroy the cc amplifier.

You may also wish to look into the services of General Development Labs up in Morro Bay, California: www.gdl-online.com
These folks make a living out of refurbishing used, failed cruise control components, and selling them for about half the price of new equipment. Once you've isolated your problem, you may find them to be a useful source of replacement parts at reasonable prices.
