:EDIT: 1983 300SD :EDIT:


So Ive been driving this car for about 5 days now.
When we first got the car we charged the a/c, and it cooled OK but I have center vents.
So after running a vacuum line directly to the pod that opens the center vents it was "good to go" well the car never got cold, I would say 70 degrees at vent on average and occasionally 60 degrees (it been in the 90's with heat index above 100).
Well after driving some the car began to "hop" when stopped in gear, if car was put in neutral or park it stopped or if the a/c was off it would stop.

So heres how today went:

1. Put vice-grips on heater core hose to help with the vent temp issue.
2. Drove around till noon with an a/c system that was a lot better
3. Drove around with friend for the rest of the afternoon with the same old suckish a/c.
4. Noticed car hasn't "hopped" hardly at all, all day.
5. Also car running right under 100, instead of its normal 80 for most of day
6. Car blows number 10 fuse(25 amp), no aux fan,compressor, or blower fan
7. replace fuse two more times in 10 min intervals.
8. Finally gave up and waiting until it cools off tonight to check a/c charge

What else should I be looking for? Its fine for 5 days, and then bam fuse after fuse after fuse????
any guidance?
