My Ford cars always seem to have this problem. I took them to the factory dealer many times. They also seemed to overheat. I finally had the radiator completely replaced by a radiator shop and this seemed to clear up most of the burning smell and overheating. My conclusion from these experiences is that the Ford radiators are not quality. Consider replacing your radiator. It is a lot cheaper than the alternative of having your engine seize. Oh, this solution was not suggested by the shops, they just kept replacing my hoses and water pump.

Check your Serpentine Belt and pulleys. The Serpentine Belt maybe in need of replacement.
The first and easiest answer that comes to mind is that there is a problem with the cabin air circulating fan. BUT - - there is not really enuf specific information. Are you sure it is a burning RUBBER smell, or a burning PLASTIC smell, or a burning ELECTRICAL smell? All could point to different problems.
what might cause black smoke from exhaust and a bad smell from a 94 ford explorer
I am having the same problem with my Ford Explorer 2011. When I accelerate to 60-65 I start smelling the smell. I have had my car in and out of service for the past year about this smell and they finally told me it is the carburator.

you probably have a bind the burning smell is probably the wire going to your starter you need to find out what it is, try tightening the starter then replace if need be
This would depend on your nose. A bad CMP sensor may cause improper burning of the fuel and can give a smell out the tailpipe. Will the CMP smell? Never. A Ford camshaft syncronizer will squeek and could cause a metallic burning smell.
The starter is burning.
