On the 1985 Camaro "IROC" with fog lamps, the headlamps may flicker on and off after extended driving with both fog lamps and low beam headlamps
on.
The load of both the headlamps and fog lamps may cause the headlamp switch to overheat, causing the internal circuit breaker to turn on and off. This
condition occurs only on headlamp switches manufactured at the extreme low end of the tolerance band.
To repair this condition, a relay should be added to the fog lamp circuit as follows:
1.
Open hood and disconnect negative battery cable.
2.
Remove left hand hush panel and lower I.P. trim cover.
3.
Install relay kit, P/N 14103317, following instructions provided in kit.
4.
Reconnect negative battery cable and check for proper operation of headlamps and fog lamps. Fog lamps should operate when the fog lamp
switch is "on", and headlamp switch is in "Park" or "on". Fog lamps should go out when "high beams" are operated, and stay on with "low
beams".
5.
Reinstall left hand hush panel and lower I.P. trim cover.
