What is your question?
I've tried running it on high with either vent or a/c mode. The results are the same.
What makes this problem better or worse?
Nothing has.
How long has your 2012 Jeep Wrangler had this problem?
It worked last winter, so not sure.
**HANDS-ON** testing is required to discover the actual failure - in reality it’s no way to beneficially assist the DIYer with online repair suggestions. Good luck!
