For those who would love to keep the original radio and cassette player in their 88-94 trucks, but don't want to pay a lump sum to get the receiver box fixed, I've fixed mine with some new capacitors and some soldering skills.
The problem with these receiver boxes is over time, the capacitors in them go bad. In most cases, the top of the capacitor (which looks like a metal canister) will bulge updard.
In two of the three boxes I fixed, the two capacitors circled in blue are the ones I noticed were bulging.
In the third box, no capacitors were bulging, yet the box didn't work properly. This can be deceiving, but there are some cases in which capacitors do go bad, but don't show any visual signs of a problem.
Just to be on the safe side, I'd recommend replacing all of the capacitors on the board.
(There are many guides on the 'net about replacing capacitors, I won't go into deep detail here.)
There are also some cases in which the box is beyond trying to repair. That is, the dreaded WATER DAMAGE! The box pictured above did have some water damage to it (circled in red). The circuit traces (line-looking things) on the board were literally "eaten" away by the water over time. Replacing the capacitors won't cure this problem. In this case, I'd suggest finding another receiver box that doesn't have water damage to it.
After replacing all the capacitors, you should have a fully working receiver box. Enjoy those cassettes!
(I have not yet found which caps are bad on the early receiver boxes with two boards inside. That's for another day.)
