What A Nightmare Looks Like
We tried the usual go-arounds and they did not work. Darn.
Found a Nissan TSB for wiring loom chafing near left wiper pivot. Oh boy! Removed engine room major
wiring loom cover to find wiring loom melted to itself in several areas. A really bad day in repairland!
In the meantime customer finally confessed to installing bigger fuse for left headlamp...so we have two possible reasons for melted wires. Cool!
Fast forward..checking continuity and power through the purge control valve back to computer (generally auto computers ground circuits NOT power them). It appears that melted loom wires imparted a current to the purge control ground circuit larger than what the engine computer could handle. Bad computer $1500ish.
We mechanics are BAD MEN.
