Hi, I am trying to locate the expansion orifice tube line for my 1990 Bonneville SSE. Can someone give me an idea as to its location? Is it behind the accumulator/drier? Is it located inline in front of the battery? I cannot locate it from the description given in the service manual. Thanks, Ren

What does the manual say?

I believe the drier is on the low side of it, so it is before that. I think it is going to be somewhere on the passenger side frame rail, near the battery. There should be what looks like a separation or joining of two lines together.

If the A/C is still working, you should be able to tell pretty easily because the line will switch from hot to cold where it is.
