I have a 2005 Pacifica 3.8 V6
I think I need to replace the thermostat. The problem is I'm not sure where it is located

 

Follow the Upper Radiator Hose to the Block. There is a Bell housing there that the Hose Connects to. Remove that Bellhousing and the Thermostat is Right Under it.

Hope that helps you out......Im still waiting on someone to at least respond to my question. So for not to impressed with this forum.

 

Please don't bash our forum. You posted at 11am and are complaining 3 hours later that no one has responded to your throttle body question. This is Saturday and I for one am out tinkering around the house.. not on the PC. It can be days before I get an answer sometimes. People are busy and there are a lot of well experienced people on this forum, you just need to be patient sometimes.

That said, welcome. I hope you stick around and learn a few things. Before you know it, you may be giving advice as well. For your TB, clean it well like Chrysler tech said and change the PCV valve for the oil problem. If it still uses oil after this, you may have other problems. If you do a search on this and the Van forum, you will see that some of these cars use oil. My town and county has used 3/4 qt in 1500 miles. OK by Chrysler standards but not mine. I have the original PCV w/ 80k miles and I will be changing it and my TB is dirty too as the wife says the pedal sticks on her as well.
Good luck,
Fixit

Welcome to the forum. Next time you have a question, if it's not directly related to an existing thread, it's best to start a new thread rather than trying to wake up and old thread like this one which is seven years old.

The first thing to do in your case would be to check the coolant level. If it's low, you won't get heat out of the heater.
