Hello from a Jeep newb!
Was driving my 1997 wrangler in the rain today, and switched the vent
over to defrost with the fan on high. The side defrost vents had very
good airflow, but there was almost none from the vent that blows air on
the wind****eld. There was also a whistling sound from that vent like air
was trying to get around an obstruction. The other vent positions (dash,
floor) seem to work fine.
What should I be checking?
Thanks,
Tom
