Jeep having trouble warming up in cold weather.
Since the winter started I've noticed my 96 Grand Cherokee 4.0L hasn't been able to warm up very well. In previous winters I could start my Jeep 10-15 minutes before I would leave and I would be defrosted by the time I came back out. But now after 10-15 minutes it will still be at the bottom of the gauge. Also my drive to work is about 15 minutes and it's not getting above 25%. Consequently, I'm still blowing cold air out of the vents by the time I get to work. Anyone have any thoughts on this? In past winters the Jeep would warm up nicely in a few minutes and the coldest we've had so far is 13F.
