I just bought a 2003 Jeep Wrangler with 30000 miles on it. On the way home from the dealer, it started misfiring. They took it back and are looking for the problem. They are being honorable dealing with this and offered to return my money. I want the Jeep. It is extremely clean for a 2003. So far they have replaced the computer, replaced the injectors, done a valve job. The computer analyzer shows that one cylinder is not firing right but no other problem.

In my 2002 toyota sequoia rear window went down unevenly and only half way. It went back up but now wont go down iat all. About a year ago had same prblem and they replaced the motor. Right now All other windows work. Local Toyota dealer service rep says its the "computer."


Can you hear the motor running when you ask it to lower the window? Is the fuse OK? If the motor is running then most likely the cable that lifts the window has snapped. If there is no noise and the fuse is OK then the motor is either dead or the c ... 2002 Toyota Sequoia
