1986 Lincoln Towncar AC on and off 155,000 miles

Last year, once last week and once this week, the AC stopped blowing cold. Twice it started blowing cold again on its own in about 1 minute. Once I turned it off, then back on and it was fine.



I think a relay is involved and it may be able to reset itself.



Is this true. Is it located behind the right inner cowl. I would like to replace it but cannot find any mention of it in the factory manual.



Thank You
