One problem related to visibility has been reported for the 1999 Jeep Wrangler. The most recently reported issues are listed below.
A/c-heater fan control switch burns out every 2 to 4 years. I am the original owner of a 99 Jeep tj Wrangler. I have replaced the fan control switch 4 times now. Each time the pigtail has fried as well and needed replacing. First time dealer replaced under warranty. Second, third and fourth time I paid to have it replaced. After 3rd time I wrote to Chrysler and explained and showed all dealer repair paper work and they reimbursed with check for one repair. Dealer gave me a credit on an additional repair. This last (4th) repair I found out that Chrysler knows about the issue, and has reduced the price of the replacement part by half. I was told to expect this to be a normal repair every 2 to 4 years for as long as I have the vehicle. I was told for a few model years they have constant power to the fan and this eventually leads to a burn out. Sometimes causing more damage if the flareup is big. Chrysler won't do any more reimb. And no plans to fix model years affected. Bummer!! repair dates: 7/2000; 8/2002; 9/2004;8/2008 part number: 55037473ab.
