Well now that winter is comming i realized that my glow plug light has not come on yet. The temp has gone down to the mid 20's and nothing. The truck starts fine. does anyone ealse have this problem

Don't know what year your truck is but.....you should see it at least
for a split second when the engine is cold started, even in warmer
outside temp.'s. I'd take it in for a looksie.

It's an 03 and i havent seen the light come on since last winter. Would the banks kit have any thing to do w/ it.

There is something wrong for sure. Is it still under warranty? The banks shouldn't affect that.

IIRC when I zapped my maxi fuse and lost my air intake heater and glow plugs the light still came on. It threw a code though. I'm going off memory here though. Oh.....it will start ok even if the temps are pretty cold without them. When you first start it up do you notice your voltgauge staying kinda low and then jumping up after a few seconds to the normal range? Even with it warm out the light will kick on for a sec IIRC. May be your bulb just dided. IIRC a tech 2 or snapon scanner can turn it on/off in the functional test. Sounds like warnatee time though.

Light always comes on ~5secs, and plugs/IAH drain power briefly, even in sunny so cal.
