Cruise control quit working

Find out which wire has been mistakenly disconnected and reconnect it.
Probably the speed sensor on a front wheel.

theyve had quite a few problems with the switch on steering wheel but also check for any trouble / pending codes will cause problem with remote start and cruise

There should be a Cruise Control relay too. Find one thats the same and switch them out, like the horn relay. If the Cruise starts working then you have a bad relay.

If the switch is replaced,then it can be wiring issue or faulty cruise control board.But as the switch is replaced,get the voltage at the switch tested to confirm the switch is actually receiving voltage.If no voltage received at switch power supply wire then ,apply external 12 volt power to the cruise control switch wire and then see if cruise control comes ON.If yes,then you know wiring is issue.

Pretty common problem with these. Here's a guide to learn how to fix GM instrument clusters yourself, I used it to fix mine and it worked great.How to guide for Impala instrument cluster repair

First check the fuse in the fuse box. It also sounds like you may have a wire in the column that is shorting out. you may have to replace the turn lever.

there is a control box for the cruise control behind the glove box . You can remove the cover by pushing in from both sides of the glove box door . the control box will be just inside the glove box to the top. it simply unplugs. any junk yard with an aerostar or ranger or explorer will have one of these control boxes fairly cheap. these control boxes are commonly known to just quit workingand are a very easy fix.
