Heater question

I have a 2006 f250 and the heater will blow cold air unless you are driving in like high way conditions. If you stop or drive slow it blows cold air only. Any ideas on what is causing this ???

I'm a newbie here and would love to hear from someone who has experienced this or something similar, thanks guys !!!

First, go check your coolant level.

Then, check both heater hoses under the hood and see what the temps are like (engine warmed). You need to determine if the problem is under the hood or under the dash.

Also, see the HVAC FAQs, linked below. They also cover your truck with some very minor tweaks.

Coolant level or a bad Thermostat. If you need coolant be sure to use the recommended product. If you need a T-Stat go with the Ford Motorcraft part. The cheap t stats dont work well according to posts on this site.
