This week I noticed an off and on electrical smoke smell when driving. It might not happen for 1-2 hours then the faint smell appears for about 5-10 seconds then disappears. I checked under the hood but didn't smell it there. All the gauges are fine, the vehicle is not running hot, no dash lights are on. What could this be?
Have a look under the van and see if you have any plastic melted to the exhaust. (like a plastic shopping bag)
If you don't see anything, I would look close around the exhaust under the hood to make sure no wires are making partial contact with the hot exhaust.
Final check would be the wires from the O2 sensors making contact with the exhaust.
You will have them before and after the converter Fairly close to the engine and no farther back than the driver seat area.
SOURCE: Very hot car.
I'd test the fan by connecting it directly to the battery to verity it is functioning. If it is, check the relays that control the fans they should be located in the fuse box in the engine bay. If the relays are ok the only other thing that could be causing the problem is the temp sensor on the radiator.
SOURCE: smoke is coming out from under my hood...checked antifreeze and oil so it fine
white smoke usualy tells about a leakage in the cooling. check that. dont forgett to refill. get it repaired or DIY. attention: could be really hot.
if it smells like fuel, a fuel line is broken. then dont drive any more since it can catch fire.
if the smoke is not white, go to the repair shop instantly.

clean the engine compartment and fill the radiator start the car and let it idle until you find the coolant leak
