ultegra shifter problem

OK, tell me there is a fix for this, please......
My front shifter on a 2004 Ultegra equipped road bike would not shift yesterday...i.e. I wanted to shift to a bigger chainring, and the shifter was so stiff I had to grab it with my right hand to attempt...it just sort of ratcheted through it's range, and did not go back to it's "rest" position.
Clearly, a cable is not connected somewhere in the bowels of the shifter. I started to disassemble, but soon got to the point, after taking off some screws, washers, and nuts, that I was not finding where the cable would actually be attached. HELP!!! Is this fixable at home?
Do I need a mechanic more gifted than myself? ;-)
Thanks,
Dave in Colorado

All I have to say is STOP, put the parts in a bag, and take it to a MECHANIC... if you can't figure out how a cable goes into the shifter you should not be working on it. Its pretty simple, and you basically just voided your warranty and may have cost yourself a $150 shifter.

Don't be intimidated by your bike. It is a pretty simple device, all things considered. Go to ParkTool and scroll down the page to find a shifter that looks like yours. You will see that the cable isn't down in "the bowels" of your shifter. It is simply threaded through a hole.

It is usually best to have documentation before tearing things apart unless you are just extremely mechanically inclined.

STI shifters aren't generally serviceable, except for clean and lube.

A stiff or frozen shifter is usually the result of a cable problem that resulted from poor maintenance or neglect.
If it is not too late leave the shifter on the bike. Downshift to the smallest cog while gently pulling the cable housing. Once all tension is released from the cable you should be able to look inside the shifter (from the left of the bike) and see the cable end. Remove the cable and inspect cable and housing for corrosion, dirt, kinks. Clean both or replace corroded cable and housing using a few drops of Tri-flow inside housing.
Always keep bike clean and cables lubricated (especially after riding in inclimate weather).
Enjoy

If the shifter had been working, it's almost impossible for the cable to come adrift and be dislodged in the bowels. It is possilbe to thread a new one in the wrong way and end up with it behind the retainer which can cause a bit of greif. Take seelye's advice and hope that you find a LBS with someone that can put it back together rather than sell you a new one. You may have had a cable or casing issue,other than in the bowels of the shifter.

It could also be the casing cables on the housing breaking through the end sleeve if it was a soft plastic one, have had that happen to me, it jams up the shifter. I agree with others that you should take it to you LBS asap.
