My 2000 jeep grand cheeroke Laredo seems to have a climate control issue. When I turn on my heat or ac it will blow as if in defrost mode regardless of what the dial is set to. Any ideas?

Have a good mechanic to check to see if the door of the a/c and heater and defroster is working properly. I had the same problem and one mechanic said he could fix it for $750. I got it fixed by an honest mechanic for less than $100. Good Luck!!
You will have to check the flap operating controls behind the centre consol as anything could be wrong from a vacumn pipe to a operating mechanism ,even the computer controlling the climatic control .
If you have duel climate control, it sounds like the blend doors inside the heater box have broke. It is a rather large repair to do. If you don't have duel climate control, look for a broken, leaking or aged vacuum line under the battery try. Hope this helps.
If you have Automatic Temperture Control then you will need a blower resistor module which could be around $100 to $200. If you have a manual temperture control then it can be just a simple $20 blower resistor.
