It should be the same layout as a '92 and a '92 doesn't require the evaporator to even be touched. I've done my '92 twice. Remove some passenger side lower dash trim, remove the glovebox and unbolt the heater box to access the heater core. Now '95's were a body change and I'm not familiar with them.

There's a fair amount of work involved, 90% of it is done from the interior. The good news is no special tools are required and the A/C does NOT need to be drained. I have done several of them, takes me about 4 hours. If you've never done one, better figure on a whole day!
