'94 AC Diverter & Comp Cycles

Well broke out the ole girl a couple weeks ago..
Had to put in a new battery, old one wouldn't take a charge.
(it was several years old)

First day on the road the AC (Auto Option Equipped)
would blow out of the defrost vents, with very very little
coming out of the dash vents. Seemed cool temp wide.

After driving for a while it "Seemed" to divert a little more
to the dash vents... "Seemed" to.

Broke it out again today and it's not very cool at all.
Checked the compressor and it would cycle, 10-15sec
on and 10-15sec off.

I'm thinking a controller problem. Because to two
different symptoms.

A little history.....the heater hasn't gotten warm for the last
several years, even after replacing the T-stat.
Sooo that also leads me to question the controller.
Maybe it's just gotten worse and has developed more
symptoms.. Any guesses?

When the heater in my '93 wouldn't blow heat, it was a clogged heater
core. A flush, and it was as good as new.

When the AC came out the wrong vents, that was a vacuum check valve. I
went through a spell of vacuum problems. Apparently the check valves get
brittle, and leak. Once they were replaced, I've had no more problems
for two years.

Hope this helps...
