Common Fox Body Mustang problems, and how to fix them! 

The one that got me for awhile was the relayswitch behind the taillight!!! 😂 i fought that car for a month then finally found that switch!!

Planning to buy myself a fox when I get my drivers license ur content really helps me in issues and how to plan for them

buying my first Foxbody tomorrow, let the journey begin

Have been around the fox since I was young and finally bought my first 85 gt hatch. Got to know it real quick and I love it. Greatly appreciate the content brotha keep it up for generations to come 👍

Door window bushings and guides, rattle when going up or down. Steel braided brake lines are a good upgrade, Stiff HVAC knobs, a little more effort turning them. Weather strip - ALL, just old & dry. Arm rest pads, worn & flat from years of use. Sagging headliners, Again 30 years old. Lights - all there not bright enough LOL. These are some of the little things with my 93' GT

The foxbody lean, seats broken! Multi function switch, resistor failure in the ecu, ashtray door, there's quite a few, but I would still pick a Fox over anything else!!

3:57 I ripped the sway bar mount bracket off the frame in my '83. Give me a winding road through the hills any day. Quarter mile runs weren't my thing.

Still running the factory quadrant when I put the 85 pedal assembly in my 79

I had to replace my clutch cable recently since it broke on me and while I was replacing it I also replaced the quadrant. Surprisingly my plastic one was still in fairly good shape

This this ignition switch is a common problem on the OBS F1 50s. I had this problem in mine 92.

I really wish someone like LMR would come out with a QUALITY heater core we can use. Everyone knows you can't expect much more than a few years out of the craptastic aluminum ones you can get now. There are so many really nice high dollar Fox builds now. This community deserves a better solution!

Biggest thing to remember when changing your door strikers. Becareful taking them out because behind the door striker is a square opening with a loose square nut. The nut can fall into the quarter panel cavity. Don't forget to use an erasable marker to outline the original position of the door striker before you take it off if you decide to replace the entire striker new. You want to have a flush door to fender and quarter panel fit. You can also keep the original strikers and just replace the plastic cylinder which the door locking latch strikes onto.

Thanks brother. New fox body father, so you have info is super helpful

Good comprehensive video Brother!

Things I have done: water temp sender for the gauge to work. The membrane for the dash cluster, headlight,fog light wiring pigtails. Ignition switch and replacement pigtail. Transmission tailhousing seal. All window rubbers and window motors. And of course, all that was mentioned in the video. However, it’s been relaxing working on it in my shop. LMR is getting my money $100 at a time😂

Live these videos. Never thought the door latches could be the rattling im hearing!

Window alignment on my vert and driver side top frame rail is sagging. Been giving my a huge headache. Still love my fox though. 😅

i'll toss in here, on 1986 Fords, the voltage regulator in the guage panel goes back after 127,000 miles. result on my turbo t bird, ranger pickup and GT mustang is you come to a stop and the temp guage pegs out. by about 130K all the gauges peg out when you come to a stop. lucky it's not hard to replace, except you have to pull the gauge panel and then monkey with the clip holding the speedo cable. after you've done one, you get how to do it :)

For the lock actuator you can just change the assembly. No need to mess with the rivet. Great video though. Almost everything you said I had to replace.

when my ignition switch went i could see how it was falling apart i decided i never wanna do that again so i bought an ford motorcraft switch...checked all the metal ears to the plastic and tighten them then put small amounts of jb weld (yes on a new switch) to hold all in place...5 years later never a problem~!~~

I’ve had like 3 heater cores replaced in mine. I bought my black LX 5.0 new in 93. So having it for 30 years I’ve done all of the replacements Caleb suggested.

I’ll ignore the Dodge in the background 😁. Looks like a 66/67 charger maybe? Pickup in dizzy going out and/or tfi module has been a thorn in my side. Had issue with the lifetime warranty ones🙄. The vacuum hard lines are SUPER brittle now. I daily a 90 GT 5 speed all stock except air filter and mufflers 225k miles still on factory clutch. Clutch cable broke replaced ign switch 2x(zip tied last one still working) fuel pump @201k and pump relay(gave problems put original back) And when I say daily I commute to work 60 miles one way 4 days a week . I don’t just run to corner store once a week lol. Ceramic brake pads, keep oil changed and keep riding!

Zip tie the ignition switch, even if it looks great(no separation) or even after installing the new switch.

That damn ashtray 😂

I’m puzzled on why the clutch pedal was so smooth when the plastic quadrant was on my fox. After it broke, I have replaced it with two different aluminum ones and the pedal is so damn hard. 🤷🏼‍♂️

That ragedy ash tray lid lol

Thanks for the info,but what's the fix for the rear lean to passenger side and why it doesn't sitlevel

Fuseable links and headlight switches

Door handles.. iv owned several fox mustangs and farmonts all have broken door handles

I wish Caleb would have mentioned the trunk pop button nit working I. 93 cars. I've been chasing my tail in this one. 😂

Always keep a extra TFI module in your foxbody ✌️

Don’t drill actuator rivet. Pop actuator out bottom of bracket, lube new rubber bushings and pop in from bottom. Any Dorman or aftermarket actuators are junk and you’ll be back in the door soon. Go to to junkyard and look at 80’s 90’s ford power lock vehicles. Can even get a metal bracket to replace the broken white plastic one

Very good stuff to go over

Is it possible that bad door pins lead to leaks when it rains?

I use the heater code video as a guide to replace my heater core

All great lil things Caleb!!! and lots more in the comments for sure lol...from the "Been there Done that" Fox Owners. Fox Platform cars are so easy to work on, some exceptions lol....I usually just roll from front to back replacing all the small stuff....Not a daily & I dont think many are any longer, I just go to LMR ..order all I need "100 bucks ish" and replace as my build moves along....Side note , has anyone tried heater cores from other cars/trucks? Id be curious to see if anything else may fit/work? Just an idea....have a great day everyone

Capacitors in the ecu is a common issue also..I had an idle issue that I could not figure out and after replacing them my problem went away

Door handles more likely the drivers side ...

The dreaded light switch, and for the hatch owners, the rear struts always quit.

I’m having an issue with my power seat on my 92. The switch has a wire that broke off. I cannot find a replacement anywhere. Or anything on how I could fix this issue. Any advise?

Air bag modules

I have not replaced any of these parts yet. Will probably have a massive failure one of these days.

Map lights

My 91 foxbody goes in reverse but won't go forward

So the foxes that came with an electric fan doesn't pertain to some of these issues

Them old stearing racks with worn out tie rods really need to be checked.Real all the rubber bushings by now should be gone by now especially in rear control arms.
