I have a 98 Explorer XLT - When the heat is on the gauge to control the tempreture does not work. If I turn it to cooler air it stays HOT! I tried the A/C and that doesn't work as well.
What could this be? Please help.
You have a very common yet very nasty problem with the heater box. Its an expensive repair but you dont have a choice if you want your air to work right. Others on this forum have dealt with the problem so they can shed more light on it.
