Anyone know much about ST225’s my reverse light is playing up. Bulb and bulb holder good. Earth to bulb holder good. I have 11.5 volts at the bulb holder tested with my power probe. But that voltage is not good enough to light a bulb. I’m guessing the switch it good because if you put it in reverse with the wipers on the rear wiper switches on. If you leave the car in reverse the light will flicker and sometimes light up after a period of time. Anyone know how it’s wired?

 

Weird one , I have replaced the bulb holder in them, can't think of anything else, really.

Other than the loom splits behind the trim on the Focus, might have a bad connection, from memory its on the passenger side.

 

I followed it along the bumper to a large plug that’s all ok. Then up into the car. All looks fine. I plugged my test bulb holder in but wouldn’t work. I may try a switch

 

Could it be anything to do with the actual switch? If it is unfortunately it’s a bit of a nightmare job to change

I’m in too minds as the rear wiper come on if you put it in reverse with the wipers on. So the switch is working that system. I don’t know how it’s all wired. I may try a switch.

 

really common for switch to fail , done a few and easy enough as on top of gearbox near selector cables

 

Yeah I think I’ll order one and try it. It’s just odd the rear wiper comes on if you put it in reverse with the wipers on

 

exactly what one of my old STs did wiper worked but lights did only now and again, so for Ł20ish whacked a gen ford switch in it and hey presto all good, and replaced one in another 225 I had too same issue

 

Brilliant good to hear that. I’ll get a switch from Ford tomorrow cheers

 

fidley job but pretty easy

 

Yeah I see it looks a bit of a twat. My works not really geared up for cars but luckily my mate will let me do at his workshop. Is that the part number for an 06 PFL one. I read there’s a few different switches

 

funny enough that was the actual switch I fitted in one of my other 06 pfl so yeah, as my current one is a late 07

 

Did you get it sorted James??

 

I ordered a switch from Ford I’ll have it tomorrow. I’ll do it at work as I’ll need to lift the car on the ramp then put a jack under it to support the gearbox. Seems you have to remove the battery, battery box and tray and gearbox mount

 

all easy jobs mate just like peeling an onion to reveal a 30 second job at end of it

 

Cars are a right chew on to work on compared to wagons ha ha.

 

I couldn’t work on cars no way. Only thing they have that’s better is cash in hand jobs after work lol. Don’t really get that with trucks

 

Was the switch new one fitted works fine now

 

knew it would be as very common fault on these volvos

 

I know I've only.started working on 7.5ton DAFs over the last few years but they are defo easier to work on than cars/vans. Ok parts are heavier and nuts and bolts are tighter but Wagons are defo easier to work on.

Glad you got your car sorted.
