1990 DODGE DAYTONA User Comment / Complaint

Manufacturers diagrams show the thermal flasher located with the fuses on the lower driver's side of the dashboard. it is not there. i have emailed dodge requesting information on where it is placed. they suggested i purchase a service manual for the car. what good would that do if the diagrams are wrong to begin with? i called dodge customer service @ 800-992-1997 a representative said there were no diagrams that would show the parts location. he said the part is located behind the dash. i have checked behind the dash and could not find it. my turnsignals do not work except in cold weather and only while the engine is cold.
