One problem related to defogger heater has been reported for the 1999 Dodge Intrepid. The most recently reported issues are listed below.
All 4 of my power windows have failed to work and have had their motors replaced at least once. The first 5 times were within my warranty and now my front passenger window has stopped working and it is no longer under warranty. My heating and cooling system locks up on occasion and keeps the heater from working. Dealer has never been able to recreate problem so can't service.
