you could buy a service and repair manual at any autoparts store. the best book out there i believe that is called hayne's service and repair manual it gives you the best step by step instructions on how to repair any vehicle.
look for a little box on blower motor it will be found on pass side under glove box. It is a blower motor resister they over heat and go bad also check the pig tail that plugs in to it ,they may both need to be replaced can get at Jeep dealer.
Sounds like the cable attached to the switch that changes the pipes to carry warm water has snapped, if you can locate this switch you can do it manually to allow your heater to work, have a look for it around the bulkhead
ahh i had the same problem, its called a blend door , they had problems with these for several years (no recall on them) they are located inside your venting area of your heat/air system , very expensive to replace it takes 8 or more hrs to replace it mine ended up costing me 600.00 to replace it , jeep wanted 1000.00 to do it.. shop around and do not go with the cheep after market ones or you will be replacing it again in a yr ... go with the one Dodge has they are much stronger than they were because of this problem they have had . lots of luck
For the 99/04 WJ Jeep Grand Cherokee there are two ways.
One is to remove the dashboard and HVAC box from the vehicle as briefly described above.
The second way to replace the blend doors is by cutting an access hole to do the repairs.
NO dashboard and HVAC box removal.
A short version of how the access hole repair is done.
Disconnect the Negative battery cable.
Lower the glove box - by hand
Remove the actuator motor - You will need a Phillips screw driver
Cut an access hole in the plastic HVAC box - You will need a rotary type of cutting tool, like a Dremel, RotoZip, etc.
Or you could do the cutting by hand with any type of small cutting tool, it will just take longer doing it by hand. Some people use a narrow pointed soldering iron!!
Remove the broken blend doors - by hand
Install the new aftermarket access hole blend door kit - easy, just slide the new doors in place - NO screws or other fasteners needed.
Close the access hole - Replace the wall piece of plastic you cutout - Apply an aluminum tape to cover the groove made by cutting the wall.
Replace the actuator motor.
Close the glove box - Your Done!
It is almost as easy as what you just read, the hardest and the most time consuming thing to do is cut the access hole. Which is not very difficult!
The job should take between 30 minutes to 1 ½ hours. Depending on how long it takes you to gather your tools, etc.
The problem is with the blend doors. Check www.heatertreater.net for diagnostic information and an inexpensive fix.
It may or may not, block heaters are not factory installed unless special ordered.
Check to see if your electric radiator fan is working. With the engine running, turn on your a/c, the electric fan should start up. If it does not, when the engine gets hot during idle, the fan must start up or the engine overheats. You will need to replace the fan.
Many instruments are used in the laboratory for heating purposes. Many are specialized for specific types of settings and reactions. Here are some of the more commonly used ones: * The hot plate- an electronic device that often is combined with a stirring function so that reactions can be heated and stirred at the same time. Hot plates come in many different sizes and shapes depending on the kind of work you are doing. * The Bunsen burner- a device that has an open flame obtained from lighting a flammable gas that is fed through the burner. These are becoming less popular in labs as safer and more stable electronic equipment is introduced. One of their main uses is sterilization of items (often glass or metal) since they have higher temperatures than most hot plates and they reach those temperatures faster. * Heating mantles- work in much the same way as hot plates but instead of just heating the bottom of a flask they heat a large majority of the surface area for an even temperature throughout the flask. Some of these even contain ways to control the temperature automatically. These devices are also reduce the risk of shattered glass due to it's ability to prevent rapid changes in temperature or uneven temperature distribution. * Water baths- use the same concept as heating mantles. These consist of a container of water usually positioned over a hotplate with the flask to be heated partway submerged in the water. These are very useful and cheap ways for heating reactions evenly but you have to control the temperature manually. These also introduce a lot of humidity to the area and there is always the risk of losing (and most likely ruining) your product in the water by tipping over the flask. * Incubators- Are used to control temperature and humidity in order to promote the growth of microorganisms for use in study like certain kinds of bacteria. These can be set to automatically change temperatures and also to turn off at certain times. * Oven-a device in the lab that can be set to many different temperatures and that is used primarily to heat glassware and other items in order to dry them. It can also be used on chemical samples to evaporate water or other residues with low boiling points. * Autoclave- A device that uses steam and pressure to heat aqueous solutions in order to sterilize them for use.
the planetary gears are locking up in the tranny. your trans case could be getting hot ,over heating the tranny or your tranny could need flushing. this is serious i wouldn't drive until it is fixed if you like your jeep and don't want to spend alot of money.

Passenger side under the dash board. That big black box which routes all of the air to the vents has to be removed.
heating of epoxies before mixing and after applying definitely helps the strength. Most epoxy instructions will say this.
Heating is basically warming something at a lower temperature and burning is heating something at a high temperature.

To answer your question, no...it's not overheating. Is yours?
When a substance is heated, a heating curve shows the changes in temperature as well as the physical state of the substance. A heating curve can chart the temperature versus the time elapsed as the changes take place.
An underfloor heating thermostat enables one to reach the perfect temperature in the house. It is also perfect for enabling the heating to turn on when the room temperature reaches low numbers.

heating
you are low on coolent, the heater core is the highest point and therefore full of air and not fluid
To measure true air temperature, not an elevated temperature from direct solar heating.
