2009-2014 Ford F-150: 2010 ford f150 radiator fan stays on

Sun, 02 Mar 2025 18:54:13 -0700

2010 Ford F150, Radiator fan seems to be running on high more than it should. Fan kicks on about 30 seconds after vehicle is started and is extremely loud. Even kicks on when its a cooler day. Also stays on when driving down the highway. Thought the fan was supposed to kick on when it reached a certain temperature then goes off once the temp drops. Switched out the high and low speed relays and did no good. I also noticed on the highway about a 30-40 minute drive the A/C was not blowing as cold as it should that I started sweating. Does blow cold when driving around town at low speeds or even just sitting there. Not sure if the continuously running fan and A/C not blowing as cold as it should are tied together.

2009-2014 Ford F-150: F150 2014 Iwe4x4 grinding and rubbing sound in 2wd and In 4wd

Sun, 04 Sep 2022 11:54:14 -0700

I have a 2014 stx 4x4 that keeps having grinding and rubbing sounds coming from the front end. Sometimes it comes when just driving in 2wd the other times when shifting into 4wd. I took it to the dealership 3 times so far. The first time they said they replaced all 3 IWE'S. The sound went away for a week. So I took it back the second time they replaced the front axle and the solenoid for the IWE. They had it for a week this time I picked it up friday and its still making the whinning and grinding sound like its partially engaged. The truck was sold to me certified pre-owned and only has 19,000 mi. Has anyone else had these same problems?

Fri, 08 Apr 2022 23:19:19 -0700

My 1999 F150, auto, 4.6 V8 loses all electrical power and the engine dies. It starts up again but the same thing happens again later. This has been going on for about a month but recently it is happening more often. Died three time this morning. So far it seems to happen when slowing down like to stop. I have maintained this vehicle, it only has 116,000 miles and in good condition. Do you have any suggestions?

Thanks,
