Heated seat relays

[Michael J Myers <mimyers@prairie.nodak.edu>]

Drivers side heated seat worked in my 86 5KCSTQ, passengers side and back 
seats did not.  Swapped relays, passenger and rear work, drivers didn't.  
Took apart both relays.  Contacts on drivers were carboned, but just 
fine.  Cleaned off the carbon.  Passenger side had some massive damage, 
melted plastic, some arc welding of the contacts, hmmm...  Decided to 
take the cheap route on this one.  Unsoldered the relay attached to board 
and soldered in a socket for an ordinary 12V SPDT 30 amp relay.  Drilled 
hole in end of case to run the wires out of and zip-tied the relay under 
the dash.  1 hour, under $10, and _all_ my heated seats work now.
