I was taking a 1986 Dodge 3500 van on a test drive and turned the AC up to test it. After just a couple of minutes, there was a poof of smoke through the vents and a odd smell. It seemed to keep running, but I shut the AC off.

A minute later, I noticed the gas guage and the temp gauge were down and not working. Surely, this is some how related.

Is this an easy fix? Thanks in advance for your help.

If the van had set for some time, and the heater core has a slight leak, you could get steam through the vents. Did it smell like coolant? Also, as far as the gauges, have you checked for bad grounds? There could be a loose ground strap under the dash. If not, I would have the body control module tested.
