Re: burning excieive amount of gas, with a strong oder of...
1st thing to do is hook up a diagnostic monitor and see what the O2 sensors are doing and at the same time run a self test on the emission system for any trouble codes ( the dealer has this sophisticated test equip), if there is any kind of problem the check engine light should be on, this trucks electronic control system is very sensitive to any kind of malfunction. What is the fuel mileage? what engine do you have? are the tires properly inflated? low tire press eats gas. Let me know and we will try and sort this out.

Vacuum leaks can be identified by spraying small amounts of carburetor cleaner around the vacuum lines/hoses & connections. Any area that sucks in the carb cleaner will cause the engine to idle slower for a few seconds. Spray sparingly & allow to dissipate/evaporate between spraying to prevent any possible fire danger. The problem you are describing could also be the vacuum resivoir having a crack in it, it usuall stores enough vacuum to allow acceleration without affecting the heater controls as yours are being affected. this is usually a cannister or a black plastic mounted ball shaped device that has vacuum line(s) leading to them located on the fenderwells. good luck
The cooling system is pretty much self explanatory hoses go from and to the most obvious places...(you wouldn't try to stretch the lower hose all the way across to the upper hose connection). The trans cooler in the radiator can actually be connected either way. It is non-directional, being a simple coil inside the radiator tank. If you want to install an external trans cooler, that's a bit different...it needs to go on the outflow side of the radiator so it can further cool what the radiator has already cooled down. An easy way to find out which side is the return line, simply take one fitting off the radiator, remove the coil wire so engine dosen't start and "bump" the engine over till trans fluid comes out. if out of radiator nipple you are on the correct side, out of hose, install on other side. Leaking lines can be partially replaced using brass compression fittings made for this. Only use them on straight clean runs, not on heavy rust or bends.
Well it seems that a leak has shorted out some of the circuits. This may be able to be resolved if nothing has suffered permanent damage, but that will have to be diagnosed by a professional with access to the Jeep.
For now, disconnect the battery keep the Jeep in a dry place so the moisture can dissipate. Use a hair drier or fan to help speed up the drying process. While this is going on, you will have to search for the source of the leak and get it fixed, the most common area for leaks is around the windshield. If no permanent damage has been caused, and the moisture is all dried up then you may be ok.
