So I have a 1998 Taurus with 169,585 miles runs like a champ. A champ with no heat that us. I got the car for free from a guy a work who said the only problem is the heat doesn't work. So I flushed it out for 5 hours yesterday after reading a write up on here about the backflush and used a prestone backflush kit. I ran water through every orfice and blew air and shop vac'd others. Even replaced the pressurized resevior. Needless to say I had clean water flowing everywhere I could. On anither note i think this was the first flush of its life so 5 hours is no lie it took forever to see clear water. Hook it all back up and all hoses in the engine bay are hot and car is running great at normal temp. It is about 68 degrees today but my vents are blowing air out at almost 30 degrees according to my thermometer. I have it on high on max heat blowing on feet and vent it is not set on max a/c but it sure feels like it. All signs point to a bad selector now. But this is my first Taurus so I'm hoping for some good feedback thank you!
