Neither 05 or 06 CRD's were available with 17" wheels was there an engineering reason for this?

Since Jeep knows that many of their Jeeps will have suspension lifts and thus larger tires installed, wouldn't it be a good idea to set up the PCM programmers used by the dealers so they can compensate for a wider range of tire sizes? At this point, dealers are very limited on what tire sizes they can program the speedometer for.

Afterall, with the latest electronic speedometer designs, it's no longer just a matter of swapping in a different speedometer gear and we need accurate speedometers no matter what size tire we are running.

When you have a choice, buy American.

OK, then heres one for ya on an existing product.

The heater temperature control in my '03 Grand Cherokee Laredo has an intermittant issue. It will occationally stop heating even after it has been working for a while. The engine coolant is full and everything else seems normal. If you giggle the temperature knob or press in slighly, the heat will return. My guess is the whole heater control module needs to be replaced. Is there anything else that could cause this issue and have you ever seen it before?

Yes, the 16" tire is the best for fuel economy.

There are a lot of after market "black boxes" out there with modified calibrations but you always run a risk of not knowing how much they validated it, meaning how safe it is for you or your vehicle.
