The contact owns a 1999 Jeep Wrangler. While driving approximately 50 mph over a bump in the road, the blower motor failed to function. The instrument panel warning indicators illuminated intermittently. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 150,000.
If hvac system is left on maximum heat setting for a length of time, the contacts in the fan speed selector switch melt causing failure of some or all of the fan speed modes and require switch replacement.
Same electrical cut off problems. Constant burning wire smell. Defrost knobs, and high med low knob stays on low or high, or nothing. Knobs and motors have been replaced 1 time. Different dealers in chicagoland and central IL say there is nothing wrong nor any recalls that have to do with this. Tired of spending money. Top of vehicle is very worn, seams are busting out and top is becoming unsafe. Driverside window zipped fell off. Jeep is garaged daily and taken care of but is falling apart.
Defroster/heater blower motor and switch quit. Replaced at least once before, within a year & a half. First, only one speed on the fan works then nothing.
