First off...Is it actually overheating? Or is the gauge just saying it is overheating? You could check the sensor which I believe is below the thermostat housing. Second I noticed you say you HAD the work done...was this at an actual auto shop or you or a friend doing this work? If it is a shop, they should be able to diagnose the problem. If a friend then have them check the resistance on the sensor. With all the replacements and repairs there can't be many problems except the sensor or the timing...If the timing is to far advanced then the engine will overheat. That is where I would go after checking the temp sensor. The timing on small engines will determine what temp the engine runs. Good Luck
Don't see how one would blow the fuse an not the other . The remote function is controlled by the BCM - body control module or vehicle interface . Regardless ,the module an the switch on the steering wheel both energize the horn relay ! Do you know what a relay is an how it works ?
Check the horn relay
VEHICLE RELAYS Operation Diagnosis
The light you see on the dash may cover other things too.Do you have your manual in the glove box.Check in it to see what is covered by the light you see on the dash.A brake warning light on the dash could be low fluid warning,but could also be a emergency brake not released fully,a service brake problem or an ABS problem etc.
Likely a bad lock actuator in the lift gate.
If you look carefully you will find a manual release for it in the back. (You will have to crawl back there.)
If your front windows work, it is not the fuse (same fuse used). More likely, either the motors have seized or the mechanism has never been properly lubricated so the mechanism itself is frozen.
if you're asking this vague without any specifics, take it to a shop and they'll do a code scan, visual inspection of the fluid's condition/color/smell, check the solenoids, etc
if your vehicle has a dipstick, pull it out and see / smell for burnt fluid... if that's the case, a rebuild is in order or a replacement
