I'm having problems with my '99 WJ Limited blowing really well out of the driver 1/2 of the vents. It feels like the passenger side vents are blowing on low at the same time.
Both sides are set at the same temperature. It doesn't matter if it is in Auto High or just High. When the fan speed is on normal Low, it is the same.
I have done the diagnostic on the HVAC panel and it didn't give a code. I have recently replaced the blower motor resistor with the new update from Mopar, and the electric fan relay because they both stopped functioning. The blower motor runs great.
Any ideas why only 1/2 the vents blow high when the selector is set to high?
I was thinking that, but after researching the blend door failing I don't think it is. Mine switches from heat to AC fine and blows real cold and real warm, just doesn't blow very hard on the passenger side.
