Should glow plug light illuminate during bulb check?

Mine comes on in my '03. With the key off, press in the trip/odometer button and turn the key to the on position. Release the button. ALL the dash lights will all illuminate and the guages do a test dance. When its over, there will be error codes if necessary.

I never see my coil light come on until around 15C (62F). I was told there are no more glow plugs, just coils.

The coil light is in the 7 o'clock position on the dash, just below the tach. It looks like a little coil and is yellow.

Not even in the bulb self test when key is first turned to the on position?

if the coil is needed, it will come on when I turn the key to on. I did not know there was a self test.

It never came on most of the summer. It only comes on when it is cool outside, below 15C

In most vehicles all the lights light up when the key is first turned on. It seems thats not so on Dodges. Only certain lights come on. However, doing the full test as FMB described does light up all lights. So now I know the coil bulb works!

now I am going to have to go and try that out.

It doesn't work for every cluster bulb on all model year trucks. The full cluster test won't light up the 4X4 light on my '99 Ram but it comes on when I lock the transfer case.

worked on my 07. thats a new trick I will have to show a few friends on their RAM's.

Be sure to show your friends how to check their engine operating hours too. With the engine off and the key on, hold the odometer reset button for 10 seconds. That doesn't work on my '99 either.

I think that only works on the diesels. Except my '99 diesel.
