You can hear them clicking, with the engine OFF (important!), put the car in reverse and put your ear against them, you should be able to hear a high pitched click. Use a person under 30 as their hearing is much better at higher frequencies (fact!)Just noticed my rear parking sensors on the spyder aren’t working, before I delve too deep are there any obvious or reoccurring problems with them or a volume control?
It's hard to tell from your photos and I've lost my recency on 4200s but you should be able to *gently* move the microswitch. Either they are screws that hold it in place that can be loosened, repostion the switch then retighten, or bend the metal arm gently so that it engages (which I cannot see).Think I have found the problem, there’s a little bit of play in the lever when in reverse, just enough to release the micro switch in the second photo. Is there anything a layman like me can do to tighten it up?
I have a lift.
Would it be the same microswitch that puts on the reversing lights (and maybe shows an 'R' in the dash?) - that would be a way of confirming that this is the problem, not just a sensor failure.Think I have found the problem, there’s a little bit of play in the lever when in reverse, just enough to release the micro switch in the second photo.
