Jeep Repair: 1999 Jeep Cherokee air conditioning, cherokee air, jeep cherokee


Question
I have a 1999 Jeep Cherokee (I know it is 4L 6 cylinder - but is that the engine?  As you can see I have no idea what I am talking about here.)

I've been having a lot of trouble with my a/c.  First the mechanic said I had a leak that they fixed;  then they said I had another leak. Then I needed a new hose, then I needed a new compressor.  So far, I've put about $1600 into fixing this, and nothing has worked.  The a/c runs cold for awhile, and then stops chilling.

Now they say I need a new evaporator, and since I've had so much work done, they will do that for $625.  From looking on different websites I think I might just need a low pressure cycling switch.

My question is - about how much should it cost to change a low pressure cycling switch?  I think my mechanic may be ripping me off. (As you can tell by now, I know nothing about cars.) I live in the NYC area, and I know it is more expensive here, so I don't expect a firm number.  But I'd like to know if I am looking at a $500+ bill or something else.

Thanks.

Answer
honestly I cant tell u where something is leaking from  that is why they are suppose to put dye into the system to see whats leaking.  Sounds like they are only guessing  and U should make them pay for what ever is needed to be fixed now because of all the guess work done thus far.
