The 1999 Mercury Mystique wiper blade sizes are 22" drivers and 20" passenger side wiper blades. See Sources and Related Links below for more information.

Be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.
Yes, a 1998 Mercury Mystique 2.5L engine harness can work on a 1995 Mercury Mystique 2.5L, as both vehicles share similar engine architecture and wiring systems. However, there may be minor differences in connectors or pinouts due to changes made over the years. It's advisable to compare the wiring diagrams for both years to ensure compatibility and to address any potential differences. Additionally, any necessary modifications may need to be made for a proper fit and function.

Also the ignition switch (what the key turns on...I'm not a mechanic I think that is what it was called) was worn and I had to replace switch.
