redcrzr Posted September 15, 2016 Report Share Posted September 15, 2016 1999 Volvo--Wipers are iffy, at best. Lately its been, operate 1/2 way up the windshield and stop, then if your lucky they just may decide to make a swipe, often times not. What I have done so far. Tested the electric to the best of "my" ability--my opinion says it checks out based on the HDT resource guide. Removed the 3 mounting bolts & the wiper mechanism. Turned on the motor and it cycles at what appears to be normal operation. Replaced the same motor and it goes back to its old bad habits. I can assist wiper operation and they appear to move with little resistance. Should I order a new motor or am I missing something? Can the motor be "weak"? Thanks for your attention & assistance.

rickeieio Posted September 15, 2016 Report Share Posted September 15, 2016 Most likely, you either have a voltage drop under load, (poor connections), or binding linkage. First thing I'd do is check your ground and lube all pivot points.

Randyretired Posted September 16, 2016 Report Share Posted September 16, 2016 A few years ago Volvo found a recall on the wiper motor on our 2001 and replaced the motor no charge. You may want to check with them. Randy 2001 Volvo VNL 42 Cummins ISX Autoshift Link to comment Share on other sites More sharing options...
redcrzr Posted September 16, 2016 Author Report Share Posted September 16, 2016 Randy Thanks for the heads up. The recalls that I could locate involved trucks from 2001-2008.

redcrzr Posted September 19, 2016 Author Report Share Posted September 19, 2016 Apparently "rickeieio" was right. I sprayed the bejesus on all the moving parts I could see. Turned on the wipers & did the "hokey pokey" with them for a while and away they went. I don't understand how I never burned up the motor because I have had this happen before and just left the switch on while driving in the rain, hoping for an occasional swipe.
