Three problems related to blower have been reported for the 2001 Jeep Wrangler. The most recently reported issues are listed below.
There is a serious product defect in the fan motor-switch-resister assembly in my 2001 Jeep Wrangler. This condition has been repaired seven times, six times unsuccessfully (the first time was in 2004, the year I bought my Jeep from a dealership) and the last one accomplished August 20, 2009 and who knows how long this will last. The problem is that the fan switch suddenly fails to operate and when the matter is investigated the mechanic finds that the blower motor, relay and switch have melted. There is some sort of electrical problem or surge which six repairs have failed to correct and my fear is my Jeep will catch on fire as has been reported in a number of cases.
Multiple failures of the heating fan blower motor switch and the fan resistor.
Failure of heating system (extremely common in all Jeeps & Chrysler cars in general) either blower switch (replaced), blower fan resistor (replaced), and / or blower fan itself. Blower switch assembly melted, which could lead to a potential fire.
