1992 K5 4x4 Blazer Electrical Gremlins
 

I have a 1992 K5 4x4 Blazer with several electrical gremlins. Here is the list of symptoms:
Windshield wipers come on briefly when I accelerate, primarily while turning left.
Windshield wipers come on briefly, and radio cuts out when accelerating.
Windshield wipers come on briefly, radio cuts out, and engine stumbles when accelerating.
Windshield wipers come on briefly, and radio cuts out when hitting a bump.

If any members have had any or all of these problems, please help by giving me possible causes and/or solutions.
And, yes, I searched the archives, and found nothing relevant to my situation.

the windshield wipers having a mind of their own have been a issue for these year trucks. usually replacing the circuit board on the wiper motor or just the entire thing would usually fix the problem but never heard of the radio doing the same thing unless they share a circuit somewhere.

my 1990 did the wiper thing, i ended up shoving a big bolt between the motor and the firewall like 3 years ago and still works somehow

thanks for your response, abig84. I was wondering if anyone was going to help me out.
I replaced the wiper motor board a month ago. No change in the problem.
The ignition switch, radio and wipers share the same circuit according to the fuse box diagram. I was hoping someone in the forum may have had the same problems so I wouldn't have to do a process of elimination with the ignition switch and wiper/turn signal stalk.
I'm retired, and trying to live on SS ain't easy. The local shops want more money than I can afford to try and diagnose the problem. Looks like I may have to just live with the problem until I can figure it out or come up with the money to get it diagnosed.

the radio thing would tick me off, if you got time maybe wire it on its own separate system with fuses. probably 2 wires touching each other somewhere but yeah electrical diagnosis is usually expensive we always have to guess where to start and spent hours tracing and checking wires
