Try some of the Toyota parts outlets on the internet. Some of them show diagrams/ drawings of the parts IE: console . From there you can probably figure it out.

I suspect that the insulator that seals the selector lever to the floor and the lever inside the car is allowing engine heat ,road heat to enter the cab past the gear lever. IT is common problem if the insulator rots or is not replaced after gear box removal say for clutch replacement.

You can remove the dash fairly easily. There are a few screws (check by the peddles and open the doors and look there for screws). The rest of the dash just literally pops off. Once that is off you should be able to get to the ashtray/inside the dash to locate said item.

You have to remove the top of center console to access the radio. Open the center console box, there is a small tab at the front. Pull up on the tab, you will see 2 screws. Remove them. Look to see where the center console top fits under the radio. Check for more bolts...Pull up on the console, and pull it back. After the console top is out, you will see another fascia tab. Remove it. If my memory serves me correctly, the A/C control and the radio both come out at the same time. Remove the 2 side vents and then you will see the bolts that holds the radio assembly. Note that the vents are in there TIGHT, be careful when you pry them out, they may break.
