Great forum. I've spent the past 2 weeks doing a ton of deferred maintenance on my 2001 (145,000 miles) and have been referring to this and other Nissan sites. So far I've done the passenger side strut, brakes, axle, radiator and rear shocks. She's driving much better now. Just have the oil cooler o-rings and the drivers side axle, strut and brakes to go.
Any way I was getting intermittent starting, so I replaced the ignition switch last night. I fired up my Pathfinder and she started just fine and I figured all was good. I was driving today and I notice my A/T oil temp, parking brake and battery warning lights are all lite up now. I didn't check the dash after I replaced the ignition switch, so I'm not sure when the warning lights came on. I'm sure the charging system is okay and of course I'm not driving around with the parking brake on. Tried disconnecting the negative terminal to see if that would reset the warning lights, but that didn't work.
I was a little worried about the A/T oil temp warning since I did just change the radiator a few days ago, but there's plenty of fluid and I'm not getting any symptoms of an overheating tranny, fluid looks/smells good, no slippage or odd shifting. Since I know the parking brake and battery lights are bogus I'm 99% sure the A/T oil temp light is bogus too.
Has anybody experienced this before? Perhaps I got faulty switch or there is a connecter in the steering wheel that isn't connected properly. I'm hoping somebody else has experienced this before I go back into the steering wheel trying to figure this one out.
