I added a half can of freon last night and the most I could get on the high side was about 170. I said it was 240 on an earlier post but I'm thinking I posted what I read it should be. not what it really was. (I didn't write it down and even when I do I sometimes doubt my figures.)
Anyhow, the pressure was over 100 this morning on both sides and that is TOO high. There are no leaks as it will hold vacuum for 3 hours.
What I did find, though, while searching the web was a defective expansion valve will cause low pressure on the high side and can cause even a vacuum on the low pressure side. With the extra freon in I had a reading of MINUS 10 on the low side.
So at this point what I want you to do is verify whether this is true as I seem to fit the criteria.
I'm not in any hurry for an answer as I can't do anything till this weekeend but if a expansion valve sounds resonable, I'll hit the accept and send you on your way.
I think I'd rather replace the timing belt or have a root canal than remove the dash to get that thing out of the evaporator. No, forget the root canal.
Thanks for your help Bill
