97 4 door 4x4 blazer. started out with rear wiper running slow at times, not at all others. then horn honking intermittently on its own. now power door locks and lumbar support inflation intermittent - seems that moving around in the driver seat affects it - lean toward passenger seat & locks buzz when you activate the switch. I have the driver seat out , console & carpet up - expected to see something obvious (cut or frayed) but everything looks fine. Any suggestions?

I did have winshield wiper stop a while back - took out motor & could find nothing. Finally re-soldered terminal connections on the circuit board of wiper motor & it worked fine. Must have had cracked solder joints.

thanks!

 

Look at the wiring under the driver side carpet. Pull it up and look for signs of corrosion. I do not think this would explain the rest of your symptoms, but it would have to do with the seat.
