Evac system, held at 29. charged with 14 oz of 134. Low side 30 high side 150 . I can only get 60 degree vent temp. Can't figure out if compressor is bad or condenser clogged. Any suggestions?
Your high side pressure seems a little low? Is 14 oz. the correct amount for your model?
15 ounces is what I show as the R134a capacity.
-------------------------
And don't forget that the hoses hold a couple ounces that you may not have gotten in there, so you are most likely a few ounces low...Hope this helps..

Tag on car states 14 +/- 4 oz . My sight glass shows clear, so I didn't want to over fill.
Wow +/- 4 oz means factory spec is between 10 and 18 oz.; thats a big spread. Most small charge systems like this one would be +/- 1 oz. Charge accuracy will depend on method used to charge (cans, RRR machine, scale calibration, etc.); how did you charge? Why did you vac and recharge?
Condenser internal restrictions would come from debris from a previous compressor failure, use of sealant, etc. This would usually show as excessive high side pressure which you do not have. Condenser external restrictions (bugs, dirt, etc.) restricts the ability to shed heat and is usually also seen as excessive high pressure. A Compressor's inability to pump would be seen as low pressure too high and high pressure too low. Your low pressure does not support this either.
Pressures provided and current answers provided indicate low charge. We would need more system history, testing data, and your reasoning behind suspecting the compressor or condenser to be able to provide much more.
