2005 cruise control doesn't work

Is the horn inop as well? If so, it's likely to have a clock spring that has gone bad. In the old days, there were 2 or 3 rings on the back of the steering wheel that made electrical contact and operated the Speed Control and horn. Since the advent of Airbags, a clockspring or wound ribbon cable is used. It's a little bit of a PITA: position the wheels straight ahead,Disconnect the battery, pull the Airbag, pull the steering wheel with a puller and there's the clock spring. Don't try to repair it - it's a safety item that's best replaced with a new one.

Not to forget this one Tracy. Also have a RECALL out on the Cruise controls for all 05 thru 11 Mercs/vics/ an Lincoln TC's.

The recall of which you speak is about Steering Control.

Actually the recall specifies Steering, Brake controls, cruise control, and a computer reset. ( Liquidated an 07 ) when found out they were doing all this on a Steering Control recall

Do you remember the recall number. My cruise ('05 Merc GM) doesn't want to turn on unless I manipulate the on/off switch a few times.

I am having an intermittent cruise control problem (not working every time ) with my 2005 Mercury Grand Marquis. I took it back to the dealer and they told me the streering system recall didn’t include the cruise control issues.
