Hi all,
1.  In trying to resuscitate the rear window washer (all pumps working) I disassembled everything easily until I got to the nozzle assembly itself. It has a different looking nut/fastener/clampette on the inside holding the nozzle unit snug to the body. Because the vehicle is in its 14th year there may be a problem of thread freeze but I couldn't see how to remove this last little piece. Is it threaded? Is it a friction fit clamp? Anyone successfully removed this without damage to the assembly?
2. I have also been unsuccessfully in replacing my 02 sensor as the existing one is rust frozen in place. It has been in about 2 years; the vehicle did sit inoperational for about 10 mos.. The present 02 sensor went in very easily when I installed it; the previous sensor spun out with min. effort.
The U-shaped pipe that it's in is not in terrible shape. It shoes signs of surface rust but no perforation. Any successful in applying an irresistible force to the immovable object while maintaining the integrity of the threads?
As always, thanks, Leo
