I have a 1991 European galdenwagon. Trying to repair a wiper system problem. The front wiper motor has no power to it. Found a fuse panel under the glove box. Replaced 2 bad fuses and it did not help the problem. Found one fuse in a remote box near the wiper and it checked good. Not sure what to check next? Is there any other fuse panels I missed or is a wiring diagram available to help out here? I am thinking a relay might also be bad? Thanks in advance for any help. John
