Four problems related to wiring have been reported for the 2001 Jeep Wrangler. The most recently reported issues are listed below.
I went to start Jeep thought dead battery and tried to charge battery guages on dash jumped around finally battery enough to turn over but would not start saw warning lite for key on dash. Engine would turn over but not start. Took to jepp dealer replaced computer module and found corroded main power feed in engine wiring harness spliced in new wire and serial data all came back. I was returning home just pulling into driveway engine lite came on along with other lites engine stalled tried to start same problem as before. Returned Jeep to dealer currently waiting for answer to problem computer does not accept my key?I brought this Jeep used that is why I am looking into any recalls or known problems of this nature.
This is one more consumer complaint regarding the heater/fan/blower wiring design failure for the 2001 model of the Jeep Wrangler. I understand that this continues to occur in other tj model years as well so I think it is a systemic design problem that if not corrected by the manufacturer will eventually cause a serious injury or death. My case is typical of the failures described by other 2001 Wrangler owners in that the heater blower fan switch began to drop speeds until only the highest speed was left operational [which I understand is how the underlying electronics specifically a resistor bank fail in this model]. Recently, this 4th speed has failed and I am not driving the vehicle until I can receive some assurance that the heater blower will not continue to heat up until it catches fire as has been reported in other instances. As I write this complaint, it is about 25 degrees outside, so driving my 2001 Wrangler without heat is not an option. I guess I am lucky that (a) it failed completely in cold weather forcing me to (b) research the issue learning that (c) this obvious vehicle defect can result in the Wrangler catching fire which has forced me to (d) go without the use of the Wrangler until a factory designed and sponsored fix is engineered and installed. So, in summary, 2001 Wrangler failed heater/fan/blower switch many other cases for this model year and surrounding model years has a history of causing vehicle fires this needs to be a factory sponsored re-engineer and recall, and needs to be done now before a fire situation causes a serious accident or injury or death !.
A/c heater blower wiring causes fire at center of dashboard. When a/c or heater is placed in high blower switchs are selector wiring over loads and causes burning. This is not an isolated case. Noted at salvage auctions many 2000 and up Jeep Wranglers catch fire in this area and burn complete. Hard to figure after fire what has happen. Im sure insurance companys would be interested in this defect. Do not know how many injurys, but im sure there has been some. I have diconnected the high position wire so that overload would not accure till I could figure a fix or Jeep will admit to a problem and a fix.
Vehicle burned down to the frame. While driving the wheel column started to smoke.
