Ford A/C :: Squealing Noise Then Started To Smell Smoke Or More Like Electrical Burning
Jul 9, 2009
I turned on my AC in my 94 ford f250 and it made a squealing noise then I started to smell smoke or more like electrical burning. I turned off the AC and the squealing and burning stopped. I found that the compressor was the problem and after pulling the pulley and clutch assembly off I found that the coil had melted or got really really hot and smelled lie it had burned. My pulley and surpentine belt were still spinning fine so what happened? My AC had worked fine a few weeks before this.

Ran the AC yesterday for the first time after a long cold winter. Seemed fine for about 15 miles but then I came to a stop and all of the sudden smelled burning plastic/electrical... white smoke started blowing out of the vents. Pulled over, popped the hood. The smoke appeared to be coming from the passenger/rear side of the engine.
Drove it another 15 miles home (had to) but with no AC or even fan on... made it and noticed the smell and smoke but only very little.
This morning I started it up .. got under the hood and clearly can smell it coming from the same area. That is the alternator at the back of the engine passenger side right? Voltages read fine... seems to be charging ok as well.
The only indicator that it is going bad is of course the smell and smoke... I can feel it is getting very hot.. too hot to touch after only a few minutes running. Spun bearings in it maybe? Just thought I'd put that out there before I start tearing it apart.

So I had been smelling an electrical/rubber burning smell on the Ex about a month ago. After a week or so I popped the hood and poked around. This is what I found!
Now I had a no start in May. The shop that I had it towed to checked the wiring harness, replaced the cam sensor, scratched the truck up and ran through 2 tanks of fuel.
I repaired the harness and all is good. What the 3 wires run/go to.
One was solid Gray with a white stripe.
One was solid Black with a yellow stripe.
One was Tan with a green strip.

I have a 93 Aerostar RWD 4.0L that I was driving around town a few weeks ago and I noticed it wasn't braking that well. The pedal is usually firm but easy to push and very sensitive...instead it was a lot firmer and didn't brake as quickly when i put my foot down. The van itself felt a little under powered, like something was holding it back and I had to put my foot down a lot more to get it up to speed. After awhile I began getting a really bad burning smell coming in through the driver window. I pulled over and saw small faint lines of smoke coming out of the front driver side wheel well, upon closer inspection I got a good wiff of burnt brake pad (I am familiar with the scent) and the hub cap on the wheel was really hot. I automatically assumed the caliper was ceased.
Later when I had free time took the wheel off removed the caliper from the wheel and everything looked fine. I was able to push the piston back in with ease using a C-clamp, but there was a lot of corrosion in and around the piston, I wire brushed it off and greased and cleaned everything up. I took it out since then on a few short trips to the store, everything seemed fine. Today however it happened again, and I began smelling burnt brake pad from the same wheel well. It only seems to happen when I have been driving it for a long time like 30mins to 1hr, short trips everything is fine. Is this the caliper or the Master cylinder? Due to the excessive heat around the wheel hub should i maybe think about replacing the inner and outer wheel bearings as well?

I have a 99 B5 v6 Passat TIP. Was doing a lot of driving around today, in & out of stores. Last store of the day go get in the Passat and now it wont start. I did smell a brief electrical burn but was unable to locate the source.
When I try & start the car nothing happens, no crank. The windows locks radio all function.
I am able to lock the car and unlock the car with the key in the door. The alarm arms & disarms without issue.
I have checked the fuses as well as the relays and they seem fine. I have replaced the ignition switch and still the same issue.
I have tried starting the car in neutral as well and no luck there either.
What is the best way to test the switch to make sure my new one isnt bad. Any way to use a jumper wire to attempt to start the car?

My father in-law gave us a 1996 explorer AWD with a 5.0 for my son who is 16. A couple of weeks later he's out learning with my wife and a very strong electrical smell took over the cabin. They came right home and when I got in I found all of the gauges not working. The instrument lights work, blinkers work, but all gauges do nothing. Pulled cluster and wires look O.K. behind it from what I can see. They saw no smoke, just smell, fuses look O.K.. What could cook on this vehicle that would wipe out just the gauges?

Today, when I returned to my parked car from grocery shopping, I noticed a strong interior electrical burning smell. Like wires burning or similar. When starting the car the yellow warning triangle came on and the hybrid warning message to pull over and park the car. What could cause this? Want to mentioned today was a very hot day 105. Up until today the car drove flawless.

I recently noticed that my car was starting to smell like oil burning off. Soon i realized that from time to time there would be a bit of smoke form under the hood I looked under the car and noticed that oil is dripping onto the cat but i am not sure from where. There is not alot of room in the back of these engines to see.

I don't know much about cars. I have a 99 Mercedes e-320 and I started smelling a burning, but when I opened the hood, there wasn't any smoke. What could it be and is it still safe to drive?

Took about a 200 mile trip this weekend, stopped at a rest area about halfway through and smelled burnt carbon, smelled like a burnt clutch almost. It was very strong and there was smoke coming from the engine. It wasn't a lot but it was cause for concern. I checked the oil, last oil change about 1500 miles ago but no problems there, temp gauge was in the middle. Let the car sit for a 10 mins or so and then headed of again. When I got home that night, couldn't smell it and there was no smoke. Car has 42K ... Also, I got an airbag fault light about 30 mins from my house.

Today was the first day I notice smoke from the wheel well, it wasn't heavy smoke but enough to caught my eye. The past few days I been smelling burning oil from that side of the car. I am not leaking oil from the motor because I check it everyday. Why it would smell and be smoking from the wheel well?

So I was sitting in my car, running, parked with the ac on and out of no where I got an electrical/burning smell coming from the vents. My volts were reading 12 with ac on at idle but once my rpms reach about 7-800 it goes back to 14. My question is what was that smell? I've had 2 alternators go on this car (power draining aftermarket accessories 3.3 v6) and have driven the car for about 2 hours collective time since the problem started (usually alternator goes quick) and haven't noticed any lights dimming, ac blows cold, system still plays full tilt. could a bad compressor be causing putting some stress on the car?

I have a 2001 Pathfinder w/ ~190K mile on it. It has been used regularly until this past winter. It has been sitting for about 3.5 months and I'm just now getting it back on the road. The battery has been draining due to non-use but I charge it and the car will start. Today I started it and after running for about 2 minutes the engine quit. When I got in the car I noticed the strong smell of electrical burning but no smoke. I did not notice this outside of the car. Upon trying to restart the car the engine just cranks with no sign of trying to start (as if there's no spark). I suspect something (probably electrical) has failed while it was idling but what it could be.

I'm having some issues with my 99 ranger. It all started on my way to work one afternoon. Going down the road I started to smell some type of electrical burning smell. I looked at my instrument cluster and seen a trail of smoke come up between the steering wheel and ins cluster from under and gear selector covers. After that the O/D off light started flashing and downshifting hard. My pwr windows and dome light also quit working. Checked fuse #26 and all my fuses before going into work that afternoon, all of them were good and none blown. After shift was over that night going home I needed to use the wipers and they wouldn't work either. Also noticed then that my speedo, odometer and trip odometer not working. I've pulled my dash and steering covers off trying to find or see anything but nothing yet.

I can smell burning oil and when stopped see oil smoke coming from the right front area. Theres absolutely no fluid on the ground ever even after sitting for days. I cant visually see any oil leak on the engine but I cant see the back. Im guessing its a valve cover leaking just enough on top of the exhaust on that side. Ive seen the gasket/plug seal set from $25 to $80. Some include the timing chain area gaskets/seals. Is that necessary to change at same time? Also, is there a gasket where the intake manifold and valve cover meet needing changed along with?

We have a 2015 Santa Fe Sport AWD (without turbo). It has about 4,200 miles on it. Recently my wife complained about a burning smell that she hadn't noticed previously.
I drove it and noticed the smell. Pulled into our garage and left the engine running and noticed a minor, but noticeable amount of smoke coming out from the hood on the passenger side. When I opened the hood it appeared the smoke was coming from the lower, back side of the engine.
I later went out and started the car and let it idle for a bit. Didn't notice any burning smell or smoke. Later drove it again and noticed the smell and a little smoke. So it seems like it occurs when the car has been driven rather than simply started and not driven.

Yesterday I made a 3 hour round trip with my car, and on the last leg coming back into town, I noticed my check engine light came on, and I saw white smoke coming from underneath the hood of my car, along with a burning smell. Luckily I was able to make it home just fine. I've googled this issue, some people have suggested coolant leak.
Also, I checked the oil levels today and they appeared to be slightly below the lowest level tick, which could be why it was having issues yesterday. Last time I got an oil change was November of 2015. I'm surprised it's this low considering I normally don't commute farther than a couple miles each day.
