Mondial T A/C Switchplate

The A/C on my '92 Mondial T will not come on. The blower does not come on at all. I am fairly sure it is a bad pushbutton switchplate because before it totally went out and was doing so sporadically, if I pressed the switch really hard (so it almost dipped a millimeter or so below the console), the A/C would engage. Then, that stopped working. Other possibilities are a bad relay in front of the condenser inside the dash (I heard that this is really difficult to access), or a bad blower motor (which I hope is not the case given the cost). After living with this for a few months, I finally sourced a replacement pushbutton switchplate part. Anyone have any experience similar to this and ended up replacing the switchplate ? Am wondering how common this problem is and how difficult the replacement is. I took a quick peek last week under the console and saw a bunch of wires, but am hoping that removal and replacement with the new pushbutton switchplate is fairly straightforward as long as I take my time and retrace every wire I remove from the old switch.

Any thoughts appreciated. Thanks.
