Anyone need thease hard to get wiring diagrams just let me know and i will email the 1 u need... Bryan: Would you send to me the wiring diagrams for a 2004 rx 330? emurphy111@gmail.com

Thanks,Bryan

Elton- I doubt that the axle failure had anything to do with electrolysis. The 2 links that Maxsteel gave you pretty much points you in the right direction. Electrolysis is very real AND destructive! Any time I had to replace a radiator prematurely (I consider anything less that 10-12 years at earliest, if the cooling system has been WELL maintained) I would test for electrolysis any time a radiator shows signs of errosion from the inside (pinhole or pinholes). The aluminum radiators generally give less problem than the copper ones did. Good Luck!

Thanks all for your comments and references to links re this matter. Am feeling a little better re axle and u-joint unrelated to the electrolysis!

Just replaced third radiator in 4 last 4 years on 2004 RX with 90,000 miles. Test for current reveals 0.5 volt in coolant and technician suggests that this is cause of radiator failures. Left rear axle came apart at outer joint 3 months ago and u-joint seizing up as of yesterday. Could current be flowing through axle and driveshaft causing these failures?? If so, how to get rid of this current? Any help much appreciated!

First things first - check your fuses. Your owners manual has a schematic diagram of all fuse layouts in the vehicle. Locate the fuse that controls the right side mirror and check it. And yes, it is very common for two of the same components (in your case, left side and right side mirrors) to be on different fuses. So one could work fine while the other is malfunctioning....

2004 with 90,000 miles; the right side outside mirror suddenly refuses to defrost; left side fine. I rely on them a lot in traffic and, of course, when backing! Any pointers as to where to look to get it defrosting again much appreciated.
