because it doesnt like you
The defroster is drawing more electrical current than the alternator can produce. It could be that the belt is slipping and the battery is margianally low so that when you turn on the defroster the alternator can't keep up and the battery isn't able to provide enough current to keep the ignition operating.
If the check engine light is on...might be a dirty EGR valve.
A person should be able to trouble shoot problems in a car. A vehicle would stall out after starting because of a failure in the fuel system, or it could be a bad O2 sensor.
other culprits could be - bad intake gasket new or clean EGR clean connections on computer monitoring circuit check battery connectors/charge main wiring harness ground is loose the timing belt needs to be replaced
ECM
It sounds like what mine did and mine was a bad coil but on a 3.2L there are 3 coils. I payed $100.00 for them to tell me this. but to find out for sure I would take it to a auto repair shop and ask them to do a diagnostic test for you.
blown head gasket
First, if you have a check engine light then have a shop scan for codes. That will tell you what is wrong. If it is bad then it will stall, hesitate, and blow out black smoke.
I had the same problem in my 98' rodeo and the tube running to the EGR valve was clogged, taking the EGR valve off and spraying carb cleaner down the tube unclogged it and it fixed the problem
stall
Stall sanitation is important to keep the animal that is kept in the stall healthy. Stall sanitation helps prevent bacterial diseases from living in the stall.
check the timing.
