Title: 2008 Marquis dash air wiring diagram?
Post by: Kathleen Schell on June 28, 2023, 02:20:35 AM

Having our dash AC compressor replaced and need some help with the wiring diagram and relay locations for the dash air, in particular for the condenser fan which has not been working for quite awhile.  The Coach assist wiring diagrams for 08 Marquis do not show ac wiring.

F83 in the front elec bay supplies 12v to the AC condenser fan and R17 is the condenser fan relay. See pg 6 of the 08 Contessa wiring diagrams and pg 7 of the07 Contessa wiring diagrams.
