CADILLAC SLS TEST LIGHT PROBLEM

1997 Cadillac SLS • 165,000 miles

OUr wipers just quit working. We've checked fuses and relay and they appear to be working. The relay was taken out and cleaned, then we replaced it and still don't have working wipers.

When you say appeared to be working did you test power and ground with a test light
1 make sure there is power going to with the test light both sides of the fuse
2 pull the relay out test power with test light there
3 put relay back in turn wipers on feeling the relay at same time you should feel it click energizing
4 if no problems there go to the wiper motor under hood near firewall take test light connect to battery +test both wires to see if you have power there if power
take test light connect to ground battery test the other wire if ground is present and hot is present you have a bad wiper motor
and also the switch should have power and ground coming in
