I have a 04 f150 FX4 5.4 motor. Here's the problem. I have no A/C or heater. The lights on the dash are not working. Also the blinker lights and the high beam lights on the dash are on. Any help

 

Idk about the lights but this summer my airconditioner stopped working and I replaced the battery and it started working fine.

 

Does the pickup start and run fine? You may want to get the battery tested to see what the CCA are on it. Also check the battery connections? Maybe disconnect the battery for 5-10mins and put it back on something may need to be reset

 

New battery. Tried to let it sit. May have to take it to my local ford dealership

 

did you check all your relay's and fuses?

 

Tried that also

 

So ford called. It's a lose ground wire behind the dash. So $113 for diagnostic test and $100 for labor and parts. 220 overall. Not to bad.

 

sounds expensive for a loose ground, but at least its fixed.

 

They had to get my dash out to get to the wire. I paid 192. I tagged it as a company truck thru my dads business.
