Re: Replacing the evaperator (93 ragtop)
No need to be embarassed. I once jacked up my home unit to build a deck underneath it and snapped the main line. Fortunately, insurance covered it. You need to remove everything next to the housing or anything blocking it. When I had my heads off, I marveled at how easy it would be to get at, but you don't need to go that far. Generally, the right wheel and lower well need to come off and removing the fender helps. Jacking the right side up will make it easier to crawl underneath so that you can access the lower bolts. The blower motor needs to come off and then take it apart and remove it in sections - the half closest to the fender first. Be sure to seal the halves and where it meets the firewall; otherwise, water will get in and find it's way into the passenger compartment as the weep hole is only large enough for normal condensation.

Suncr,
Thanks for the response. If it was my home unit Id be a lot happier. I do that for a living. :D HVAC contractor. Anymore I dread doing about anything to this car. Everything seems so hard to get at.

Re: Replacing the evaperator (93 ragtop)
I had to replace mine because I damaged it when replacing one of the AC hoses. It wasn't that bad a job. As said above, remove the lower fender and the wheelwell panels, windshield washer reservoir, etc. The nuts that hold on the cover at the bottom are accessed from under the car. If you're thinking of replacing spark plugs, this is the time to do it because the dreaded rear passenger side plug is easily accessible.
One particular word of caution: be very careful when removing the cover not to damage the heater core! I manhandled the parts to get them out, and I ended up breaking the solder joint on one of the heater core pipes. As a result, the heater core leaked, and I had to replace it, which was a much bigger job than the AC evaporator core. So in replacing the AC hose I damaged the evaporator core, and in replacing the evaporator core I damaged the heater core. Talk about a lot of work to replace that AC hose! Be careful.
