1991 Ford Tempo heater

Here is a photo of the heater assembly.

I'M A JEEP GUY

I'VE DONE SOME MODIFICATIONS TO MY HEATER(S) OVER THE YEARS

THE DIAGRAM YOU WERE JUST SENT BY JohnnyT73 SHOW THE ACTUAL HEATER BOX, THERE IS ADDITIONAL DUCT ABOVE THAT - I DO NOT HAVE A PIC OF THAT

I MODIFIED JohnnyT73's DIAGRAM SLIGHTLY - SEE MY 1ST PIC
.
.
THE REMAINING PICS ARE OF MY JEEP, I'M SENDING THEM BECAUSE IT IS A REALLY SIMPLE SET UP AND YOU MIGHT UNDERSTAND HOW THE HEATER BOXES WORK IN GENERAL

- I DID FIND A WAY TO RECIRCULATE MY INTERIOR AIR WITHOUT THE NEED OF USING OUTSIDE AIR TO PUSH THRU MY HEATER CORE (SORTA A AMERICAN MOTORS GLITCH THE WAY IT WAS DESIGNED) BASICALLY I MADE SOME MODIFICATIONS TO THE HEATER DOOR ON THE PASSENGER SIDE. (NOT SAYING IT WILL BE THAT EZ FOR YOU!) BUT NOW I CAN RECIRCULATE THE INSIDE AIR, AS WELL AS STILL USE THE SYSTEM AS IT CAME FROM THE FACTORY

THE "COLD AIR" PART FROM OUTSIDE AIR IS MOST LIKELY YOUR PROBLEM WITH A PROBABLE "TORE UP HEATER SYSTEM OF SOME SORT"

SEE-UNS HOW YA'LL HAVE DONE SOME MODS ALREADY, I'D SAY YOUR GOAL IS TO SOMEHOW CLOSE THE OUTER DOORS. THIS MIGHT INVOLVE TAKING CABLES LOOSE/ DISCONNECTING VACUUM MOTORS OR ELECTRIC MOTORS, AND "TYING/ WIRING" A DOOR SHUT. LIKE I SAID, I HAVE NO CLUE ON HOW YOUR DOORS ARE ACTUATED

IT SEEMED YOU HAD "AIR FLOW" PROBLEMS, BUT THE "HEAT" WAS FINE (IF YOU COULD USE IT) SO I WON'T GO INTO A "STOPPED UP HEATER CORE" POSSIBILITY

REMEMBER #2 PIC THRU THE END, IS OF MY JEEP- NOTE THE DUCTWORK ABOVE THE ACTUAL BOX THAT GOES TO MY HOOD VENT. LOOK AT MY DOOR POSITIONS

AS YOU CAN SEE, I HAVE NOTHING MUCH TO DO! THERE WERE ANOTHER 10 OR 12 PICS I MADE, I DID NOT THINK THEY WOULD AID YOU

KEEP US POSTED ON PROGRESS

WELL

MAYBE A COUPLE MORE

THEN WE HAVE THE "EXTRA HOMEMADE HEAT SOURCE" THE "SAHARA BREEZE", FOR THOSE I WANNA SWEAT COLD TIMES!

Im a Ram (Dodge) truck person myself. I currently have a 2003 Dodge Dakota 4.7 4x4 quadcab 151k miles. My truck before this was my favorite and HATED to sell it, but having a single cab truck wasn't working out. It was a 1989 Dodge D100 (last year of that model) 318 shortbed with 69k original miles a/c, cruise control, and overdrive trans. GREAT looking truck. Got a lot of compliments. Before that was a 2003 Dodge Ram 1500 5.7 Laramie 4x4 with 43k miles quadcab. Im currently dieing to own a new 2014 Ram 1500 Ecodiesel. What a workhorse of a truck and get 30mpg.

JohnnyT73's FIRST DIAGRAM

LEFT SIDE AND "CLOSE" IS THE FIREWALL/ ENGINE SIDE

PAY ATTENTION TO THE HEATER CORE'S CONNECTION PIPES - THEY ARE ON THE ENGINE SIDE

AND

MY JEEPS,

"MR. JEEP"

AND "WILLY"

IS ANY OF THIS HEATER STUFF MAKING SENSE?
