Three problems related to wiring have been reported for the 1997 Jeep Cherokee. The most recently reported issues are listed below.
Vic display show "coolant sensor bad. " online investigations reveal many owners have experienced the same problem over the years. Their trial solutions have ranged fromn replacing the "coolant temperature sensor," the coolant level sensor," replacing "connecting wiring" to the vic, and to removing the vic to repair solder joints and cracks at the circuit board that is located in the vic. Most report that the first three attemped remedies did not resolve the defect. Some report success in re-soldering joints on the circuit board. The latter,--removing the vic and repairs at the circuit board-- is an involved process and requires extensive knowledge and repair tools and equipment. All report that this condition left unresolved could lead to the engine overheating and/or faulty data sent to the fuel injection system, and possible engine fire. With so many complaints on this defect, a recall or a manufacture repair bulleting, should be issued at the manufacturer's expense.
Blower motor failed at 78k miles excessive liquid draining when running ac was told that motor had been "redesigned" and that parts alone would cost over 300. 00 because in addition to redesigning the motor, a new wiring harness has to be installed!!! remember the 300. 00 is for the hard part and wiring only, not the labor to install. . . This is completely ridiculous when a motor for the same model manufactured a year earlier is only 20. 00!!!!! as far as the excessive liquids running from under the vehicle while the ac is running, this site was the first indicator as to what is wrong with it. . . (I simply though it was a design flaw) also this complaint has been edited to let you know that "running boards has nothing to do with this. . . It seems one has to go through the process flawlessly or begin again completely!!!.
Wire harness has burn marks due to excessive heat from the engine. Dealer notified.
