Sadly, attending to the vacuum swap could be a dilemma, when you have found. I don’t would like to say “yeah, start out ripping stuff aside” as I simply cannot actually respond to that question — only you may know When you have the aptitude to disassemble issues and be capable to place them back alongside one another. If you really feel you can take away a distributor cap, and many others. and put them back just after, Opt for it! You’ll save yourself a ton of $$$ performing it on your own.

Travel the vehicle on to a flat region, jack up Click Here To Investigate the front conclusion, and spot the car on jack stands. Be sure the steering wheel is unlocked.
The first thing to check, though, are your fuses. If there won't be any lights to the dash, then you may not have “logic” power for the TCCM (logic electric power is +5VDC). The logic energy is supplied through the courtesy lights (do your inside dome lights come on after you open up the doorway?
