I know this common problem has been covered a lot but I have a few suggestions that might help.
1. Make sure the coolant level is up in the overflow tank located on the
drivers side firewall.
2. If you not sure if your DCCV (Dual Coolant Control Valve) is working
disconnect the elecrical connection as this will let the valve move to full
heat. (no power to the solonoids)
On the 6 cylinder models there is a connection a little higher up the radiator
shroud that is easier to get at, this works only on the 6 cylinder models
on the 8 cylinder models this connector also suplies power to the
auxilairy coolant pump and you do not want to disconnect this so you have
disconnect the power at the DCCV which is a bit difficult to do.
Of course all the actions as bleeding the system etc.etc. still
apply.
