then you need to find, purchase, and install a new switch. on a car that old, this will be about impossible. you are going to have to find an used one in a junkyard, there are lots of folks who sell used car parts on ebay. I suggest you go there and find a vendor selling used parts, tell him what you want and he will put it on his list and put up an ad when he locates one. note again that due to age the used part may be in the same shape as yours.

very easy just go to reliable-store.com it has all manuals there many other websites also but in this matter this website is too good

Since there are so many different cars and so many different engines,the manuals for all of them would be very expensive.All you really need to do is call a Cadillac dealer with your make,model,and engine size,and they will most likely tell you for free.If they do not,try a AAA approved auto shop.In my opinion,AAA approved shops are BETTER than dealers because of their wide range of vehicles and the standards which are required to maintain AAA status,not to mention cost much less.If you have any questions or need more help,just comment here and I will get an autolink to your post and reply ASAP.I really encourage responses so I can follow up properly as I know where you stand and asking someone else restarts all the explaining because we cannot see other 'Expert's' responses.Good luck,Greg

Then you need the book to check wire location, firing order, timing, etc. New wires is always a good idea, old wires can fail. Wrestling around in there you may have bumped a wire or vacuum line loose.
