I would like to know where is the truck turn signal relay is located....

Check you bulbs first because a bad bulb will cause this also !

the is called the CEL , check engine light , aka. SES or MIL.
in the USA< the EPA mandates that flashing,"OBD2 rules" SAE.org.
it means :
your engine runs so bad, (misfire,etc) that the rich mixture
will burn the CAT up soon.
it says in the operators guide, if you choose to read it.
to drive slow, remove trailers and loads. and get it fixed soon.

this is to avoid the $1000 bill for a new CAT.

best and first replace bulb

Hey I don't mean to condemn your car, but what you have is a GM vehicle not a real Isuzu. The real Isuzu was a lot more easier to work with and much more pleasant to drive in my opinion. Anyway, there are a few screws holding the armrest and the door handle plastic flange that needs to be removed first. Then you can pop off the door panel, which is just snap fitted. You might have to look hard for the screws and even use a flat screwdriver pop off the small plastic pieces hiding the screw heads. Make sure you don't try to pop off the panel before removing the screws as this will irrepairably damage the panel.

The fast flashing normaly means that there is A light out it does not mean it is that one, It can be front or back. This video should help with the install. http://www.youtube.com/watch?v=4ewEB890UFo

When you press the car's brakes Follow the truck Isuzu A vibration in the front of the car
