I would check the dimmer switch adjustment on the column

Did they work before the turn signal witch was changed out? The dimmer switch hooked up electrically. Usually the switch itself (mounted on the column) doesn't have to be messed with during a turn signal switch change out since the turn signal switch is at the top of the column, but the actuator part is in there and it can be tricky to get back into place. That's the problem child area I'd look to.

Looks something like this below. Has a weird shaped plug that goes into it, and an actuator that operates it from the pivot on the wiper stalk. Listing covers pretty much a wide range of cars, but definitely fits your 85 as it fits all G-body columns if you need to get a new switch. I still think it's the actuator in the pivot.



If your actuator up in the column needs replacing, it's GM p/n 7827028:



Sometimes when reassembling crap on the top end, the actuator rod and actuator above don't meet up properly or things slip out of place and that's not good. Not saying that's the case, but if you're not paying attention, things could get hosed up.

Check to see if the switch operates, you should be able to see if the actuator rod is actually operating the switch. Reference pic below.

Whoever put the turn switch in f-ed it up; take it back to them. Sounds like they didn't engage the stalk correctly.
I may look at it myself is it hard to tear apart the column to get to the switch?

They did work before the turn signal switch was replaced and when you say dimmer switch are you referring to the guage cluster dinmer if so mines not on the coulum

You can scroll through this repair to a tilt column in a GM truck which shows the actuator end by the turn signal switch pivot (personally I think he uses way too much grease, but to each their own). There's the top end of the bent actuator rod that sits in a slight groove in the actuator plastic piece. Many times during reassembly, this alignment isn't maintained and the rod slips out of position.

Again, not saying this is your problem. Just something to consider.


Also, review this video by oldsofb . It's very good. Gives you an idea that it isn't real simple if you've never done one before. (around 20 minute and 37 minute marks he discusses the actuator disassembly and reassembly respectively). But watch the whole thing, it's educational!

No. I'm talking about the headlight high beam dimmer switch. All on the column.

Thanks for this information i hope that this solves my problem im also not afraid to tinker with things!
