Removing Evaporator on 98 Grand Marquis

I've got a very small leak in my A/C system. I have not been able to spot any UV glow fluid coming out anywhere. The only two places I can't reach with my blacklight are the evaporator and the top of the compressor where two lines interface with it. I'd like to take the evaporator out and check it, but my Haynes manual has absolutely nothing on this. I can start just taking everything apart, but it would be nice to have some idea of the most direct way of removing the evaporator. Can anyone help please?

Re: Removing Evaporator on 98 Grand Marquis

if your not qualified to do this and do not have a recovery system don't try it. That is
why it is not covered in the manual. You cannot repair an evap. Must be replaced. Evaps very rarely leak. I'd be looking at the compressor. If you are not qualified send it out. What ever you do DO NOT pump in a sealer. There are ways to check an evap. with
out taking it out but you need special tools and fittings that you will likely never use again. Good luck and no offense.

As stated above if you don't have the recovery equipment leave it be. The dye doesn't always show without a black light. I would look at the dryer carefully and use a leak detector at the front of the compressor. Way more common leak are and easier to start checking there. If you have a leak detector can check at the A/C drain for signs of leak.
