i successfully installed a new heater core and blend door yesterday in my garage. This was the bigest job i have ever done by myself on this truck and i wil tell ya idk if i will do it again. Once i got the heater core and the entire dash put back in, i bolted in the steering column. everything was going good until i saw this one wire hanging there and i cannot for the life of me find out where it goes. can yall help me out?

I posted photos of this wire/connection in an album on my profile labeled heater core or something like that.

Thanks guys

 

My first question is, "is everything working?" If so, this may be a redundant connection that was part of your wire harness. Manufacturers may find it cheaper to use a common wire harness between trucks with different options, leaving some connectors hanging loose but buried behind the dash.

 

yes, everything is working like normal. I bet you are right. Now my oil pressure is reading high and i dont know why. Any guesses?

 

I'm stumped. I would think that if this connection was related to the oil pressure gauge, it would't work at all because it wouldn't be plugged in.

 

As am I. A mechanic told me that wasn't an important plug do its fine unplugged, if it even has a spot for it to go. Trucks runnin fine but the gauge is still screwing up. I started another thread with more details about what's goin on

 

your post is very discouraging to me because I have a 2000 V6 F150
and I am just now exiting from an entire winter where I had NO heater
in my truck. Let me tell you it was brutal and embarrasing. It is bad
when you have to wear a snowmobile suit and gloves to drive your truck
in the morning. Almost as bad is no defrost capability in the windshield.

I guess I need to go to south Florida to sell it :-)

I am afraid to ask the dealer how much to fix my heater.....

Can anyone hazard a guess as to how much money to fix ?

 

i have the same truck, and i just recently pulled entire dash out, and put it back in, its not possible to plug thing in wrong or plug one in where it don't belong. double check you ground, and go through and unplug other connections to the dash panel and plug back in. then pull out dash panel and check to make sure all connections in back of dash panel are connected right. and yes there is maybe one or two plugs that don't go to anything.

 

About $700 in my area give or take a bit ! A weekend , 24 pack of your favorite beverage and you can do it yourself ! I can do one of these in about three to four hours , depending on lunch break ....
