98 f150 a/c problems
My 98 F150 does not blow cold, and being in Texas that really sucks. I have completely drained the system and refilled it. Only thing is that on the low side the PSI is really high on on the hight side it is really low. I changed my orifice tube, that looked pretty good. I took it into my local service shop today, they came back to me and said that the a/c clutch does not click on so they did some diagnostics on that, wiring etc... and just now they called back and said that there is a major leak coming from the evaporator inside the engine compartment and also its really bad in the cab. total cost to fix it would be $1,800. Anyone have any ideas on what I can do to get this to at least blow cold for a little while, and still have a little leak. Don't know if i change the evaporator if it would really slow the leak down, seems like the leaks are in the tubes. Staring to seem like a lot of work, wanting to fix it enough to sell it and get a new one now.

The parts are expensive, I would buy the parts and replace them your self then go to a shop to have the new ac propely installed. If you don't suck everything out before you install new coolant it will cause it not to work properly. there is a machine that when installed it will suck every thing out, hold for about 5 min to se if there are any leaks, if no leaks it will fill the system to the proper spec. since there are so may problems you will need to replace the driyer as well, it's job is to remove all the water in the system out and store it once it get full you have to change it. but since the system has been broken already I would do that hopefully you did not mess up the new orifice tube.
