Wiper Problems Posted by dave24 [Email] (#457) [Profile/Gallery] (more from dave24) on Mon, 20 Dec 2004 09:24:05 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I'm hoping that someone might be familiar with this one. The car is an '88 900TC. The problem is slow wiper action - actually comes to a stop mid-stoke, and will start again slowly by turning the stalk to off and back on again.
My first thought was binding linkage, so we replaced the wiper transmission with a known good one (linkage moves freely; no binding with the motor out). Also replaced the motor with a working motor (the old one worked but changed just-in-case. The same symptoms appear.
We replaced the wiper blades with new ones. That helped some, but the underlying problems continues to exist.
We cleaned the contacts on the wiper stalk - they were pretty clean though and didn't result in any change.
There is an intemittent mode plus slow and fast (although hard to differentiate given the current working condition)... so I'm ruling out the relay. (My logic could be flawed here though).
So now I'm stumped. I'm thinking this might be a ground problem, but everything else electical seems to be OK. Any thoughts or suggestions woudl be welcomed.
One other side note (almost forgot this)... the windshield washers recently stopped working. Not a clogged line, and I don't hear the motor operating when you pull the stalk, so I've suspected maybe the motor might be bad, but I haven't yet pulled this out. Maybe this is related...??
TIA,
Dave
