1st post here but have read a lot of threads. Jeep is a 2012 Wrangler Sahara. It's a Canadian model but that shouldn't change things. The left dash gage with the MPG, caution advisories, temperature, etc. is intermittent. It may or may not come on when starting and randomly will come on showing the readings. The back of the gage is buried deep under the dash and not readily accessible I suspect a loose connector but not sure where to look either under the dash or engine compartment. Any suggestions, Thanks.
