I know, why do I even need working wipers, I shouldn't be driving in the rain right... but here it is anyways, my drivers side wiper works perfectly, but the passenger side wiper moves inconsistently. It'll move a little, then stop for a bit, then move again, all while the drivers side is moving fine. There is a clicking noise coming from the wiper control module every time the passenger wiper moves.
I tested the wiper motor according to the shop manual and it works fine (both low and high speed). So I'm assuming it's the wiper control module, but the shop manual doesn't say how to test it. I could use some guidance here, how do I test the module? Has anyone run into this problem? Do you know where I can find a replacement module (without having to take out a 2nd mortgage)? Thanks.
This sounds dangerous. When functioning properly the goofy action of the Viper wiper blades come within milliseconds of colliding in an odd sequence and always make me nervous. You'd figure the engineers would build in some level of fail-safe so they never collide. I can easily see that causing the engine to explode.
I've never taken apart a Viper relay control module for wipers. But for other cars I've seen anywhere from cracked cold solder joints that need re-soldering to sticking relays, or carbon buildup on the relay contacts. Of course I'm a master at attempting to repair/recondition the existing units before purchasing new.
Has this vehicle seen ample rain? I'm guessing most don't drive their Vipers in rain. I lived in Washington for a while and constantly used my wipers and haven't seen any oddities yet.
Thanks for the replies, especially Dave for the beer offer... Dirtbag, the wipers have seen very minimal use in their life, so it is odd. Dirtbag, you've inspired me to open the module up and try and fix it first. Now that you mention it, the sound coming from the module could be a relay sticking... I'll let you know what i find. KNG SNK, I'll PM you once I break the module...(BTW it's a 94, forgot to mention that)
The modules I have are from a 99 and a 97. From the 99 I have 3 modules that came with the car. I would have to test them to find out which works. From the 97 I have 1 that does work. You would have to cross reference part number for compatibility.
