Hi there,
I really hope that someone can give me some advice! I am getting near my wits end with this one!
I have a 1990 Corolla. Occasionally when driving in the rain my wipers stop, I have encountered this problem 3-4 times now and I really need to get it fixed as it is unsafe.
The problem is encountered when I attempt to put the wipers on (any setting) and I get no response. Completely dead. So far I have tried the following:
1 - Checked the fuse. It was fine except for one time, I think this may have been caused by me trying to troubleshoot the problem, I was unplugging/plugging the wiring harness to the wiper motor whilst the wipers were on. At any rate I replaced the fuse and it has not blown since. 2- I checked the connections at the wiper motor. I was surprised to find the harness unit full of a white putty-like material, thinking this could be causing a bad connection I cleaned the unit with an electrical cleaning spray. The contacts are now clean and all contacts look good. 3- I purchased a multimeter (finally) and last time the wipers stopped I pulled over and checked the voltage at the wiper motor (I checked this previously when the wipers were working so I would know which terminals I should test). Nothing, 0.0V. No power getting through? 4- Grounding. I thought that perhaps the circuit had a bad ground. It looks like the motor is grounded very near to the wiper motor unit. This connection appears to be good.Help!!!!!
Also, I don't know if it could be related but, occasionally when putting on my turn signal I get a noise from the steering column, it sounds like a bad electrical contact. Should I investigate this ?
Thanks in advance for any suggestions or advice that people might have.
Charles.
