I think I fall into the classic "need to replace evaporator temp sensor". I have read Steves posts on the subject and it seems to match up.

Symptoms:

Ac will run for a couple mins then shut down. This happens intermitantly. I can have no ac...stop and get gas and then have ac.

when ac is running fine - reading 5 is <135.

when ac shuts down - reading 5 is >140.

So I've looked for instructions on where this part is and how to replace it. I know generally where it is (under the dash) Thanks Steve... but i don't know where exactly. I just need a couple of pointers and I'll be on my way.

Thanks,

Paul
