A lot more involved then other poster suggests. 2008 ford escape has ford smart charge system - computer controlled, check for DTC's - diagnostic trouble codes first!

Trunk ajar switch could be faulty . 2008 model would have a DTC - diagnostic trouble code stored if it is a electrical circuit fault . Take it to a qualified technician that has a factory or professional scanner that check these code's .

Diagnostic Procedure Before Repair
Step 1 - Clear all DTC's with a engine scan tool (diagnostic trouble codes.) Visit - Scan PCM
Step 2 - Start the engine and observe the MIL, if it does not illuminate continue to next step (service engine soon or check engine light.)
Step 3 - Drive the vehicle while trying to maintain a constant throttle position as it accelerates up through all four gears. If the transmission is shifting properly, it should be in 4th gear by the time you reach 45 to 50 mph on level ground. Repeat this procedure from a standing start 3 to 5 times. Rescan the PCM for trouble codes, if none appear the problem could have been a onetime occurrence. If a trouble code has returned repair as needed and recheck system. Hope This Helps !!!
