One problem related to defogger has been reported for the 1998 Lincoln Town Car. The most recently reported issues are listed below.
While driving home from work began hearing a clicking sound pulled over called my husband he came out decided it was safe to drive home, started the car the next morning the heat was blowing at full speed could not turn off had to close all vents and ride with all windows down, took car back to dealer they informed me that the heating& ac had a broken peace took to the shop and paid a little over $1600 to take out my dash and replace it this was 2004. Last month the same thing has happened and I don't feel it's fair that I should keep replacing a faulty part at $1600 an incident Lincoln should pay for this part to be replaced since it does not come from normal wear but a cheap part put on a not so cheap vehicle.
