EA Ghia Cruise Control Not Working

Well, for some reason RACV didn't pick this up which i'm pissed about and wanna know where I stand. The problem is when I turn it on the dash light comes on and says it's working but it will not set, even at 80km/h I can't get it to work. Any ideas?

Could be anything man. Could be as simple as the hub buttons not contacting properly, could be a fouled brake switch, vacuum leak between pump and actuator, broken cable or broken actuator pump. Check your cable out first, to check mine is working, i disconnect the vacuum line at the pump end (behind washer bottle) and suck air thru the line to check the throttle is opening properly. To check yer set/res buttons u need a multimeter... resistance should be 1K and 330Ohm from the yellow wire in the plug under the steering column.

Usually just dirty contacts in the switches. Lever them (the buttons) out of the steering wheel boss with a small screwdriver and clean the carbon contacts by rubbing them gently 2 to 4 cm across a sheet of normal white bond paper. DO NOT rub too hard, DO NOT use abrasive material (ie sandpaper) or ESPECIALLY DO NOT use any sort of spray cleaner or lubricant or you will remove all the carbon and kill the switch.

"Silver plate???" Where? The carbon contacts are on the underside of the plastic switches usuallu the contact plate stays in the boss but otherwisew they shouyld come apart easily.

dont know if this holds good in EA's, but certain cruise controls are connected to the brake wiring... so if you blow out a brake light, the cruise control will not work...

Yeah, I have a temperamental brake light. I don't see how this can stop the system from setting at all though?

The vehcile brake switch is separate from the cruise brake switch. Its combined with the vacuum release valve. So i dont think a blown brake bulb would have much effect on the cruise system.

well, the cruise control in my car (aftermarket) will not work if the brake light goes out... it works on the principle that when you press the brake, the brake lights come on and the cruise control is hooked to the brake light line, so if current passes through it, the cruise shuts off... (or something to that effect...) i know my cruise control didnt work for a while, and when i rang the company (electric life) they asked me to check the brake light and sure enough, it was out... new bulb and cruise control was back online...

but as brent said, it might work on the vaccum release valve which is how it must come from factory... (and i have no idea how it work!!)

Re: EA Ghia Cruise Control Not Working

Oops I have since found some cars within the same model run used mercury switches instead. So if you find shiny metal mercury switches under those buttons spray away to your hearts content - it won't help but it won't hurt either.
