I would think this is old news. I thought I saw a post that was relating to this issue.

CPU Damage from Water Leak

Some early RX7's have had CPU damage caused by water leakage. Symptoms include:

erratic or no horn
erratic turn signal and emergency light operation
erratic or no 'beep' warning signals

Leakage occurs around a metal flange (upper left inner body under left fender)
Fix from Mazda:more sealant applied to area during production and protective coating added to inside of CPU.
Field fix; sealant applied to area, replace CPU if damaged beyond cleaning.

I have had to repair a few of these, I would think they have all been taken care of by now. Need to check CPU and fuse block for water damage also.
