In the old days, when the recall for this first came out, they thought it was water getting into the module, ruining them. The instructions were to glue the cover back on with silicone sealer. You may have to cut and dig it out.Did you have to dig the module out? I tried to do this repair a while ago and I quit because it seemed the module was epoxy'd in. Is there a trick to it? I'm just sitting on my new module and my wipers still act funny here and there.
