A/C and heater control Fixed

To fix my constant heat on problem, I had to get to my heater control panel and adjust the cable (it slipped). I added some epoxy to keep it from slipping as the heater control cable is not routed correctly and is under tension when everything is put back together. Turning it to full cold caused the cable to slip on the clip fastener. The epoxy will hopefully keep it from slipping. I was able to get at least the #2 fan speed to work. I keep it on Cold. Haven't tried to switch it to hot yet, then back to cold.

The A/C works great now. I was able to buy some cans of R134a in Idaho, and added R134a until it was full and at recommended max high pressure range.

Driving at 65 mph up to 70 mph to work and back I have been getting this mpg this week:

mpg To work:-----mgp from work:
62.9---------------52 (with errands and extra stops)
63.3---------------58.6 (windy)
65.0---------------61.7
63.7---------------
I still coasted this week, but only the long sustained coasts. So 55-60 mph (right lane) commuting saves about 3 - 4 mpg on average than 65 -70 mph (left lane) commuting or about a 5% savings in fuel. So about a $1 savings per week in diesel if my math is right. I will just keep it at 65 mph for now.

Traffic has not been a factor so far.
