   The evaporator is leaking and apparently is a known issue from ford and they didn't report this. The evaporator core is leaking and it blows hot air for a good amount. It draws a lot of power form the system and drops the rpm below idling. Forcing me to rev a cold engine so that it does not stall out.

   The weld that connects the clutch pedal bar to the tube it pivots in broke on my 2015 Mustang. This makes the pedal wobbly and can prevent the clutch from being fully depressed. For months, the clutch was squeaking. Upon inspection, I noticed the weld was broken. I have not been in an accident because of this, however, the clutch pedal is now loose and can at times hit the 'neutral' switch (which measures full depression of the clutch to allow the car to start), which…
