| Post subject: | wiper motor part #'s, compatibility |
I have a 73 Dart Swinger with a 2 speed wiper. In replacing my gauges last week, I inadvertenly ruined my wiper switch. It was not the original wiper switch, it was a 3 speed. I have no idea what the switch came from. The numbers on the switch are 348876 23199 It worked fine and the spades lined up with my plug. So, I found a 72 Duster at the boneyard, grabbed the switch, but the spades didn't line up properly, so I returned it. So, I ordered a "73/74 Dart NOS wiper switch" from ebay ($15+$5 shipping), but the spades don't line up, same pattern as the 72 duster switch I had. The numbers on this switch are: 3488839 23199 My question, does anybody have a correct part number for my car, or a switch they want to sell? Is the part number on the supposed NOS switch I got actually for a 73/74 Dart? (BTW, it is in great shape) What year range are wiper switches compatible? |

The 2sp system uses a different wiper, harness, and switch than the 3 & variable speed system. While I have mixed & matched parts of 2 and 3 speed systems over the years for a number of the Tidewater Mopar Club giveaway cars (http://www.tidewatermoparclub.com), it's tricky and I generally don't recommend it unless you know what you're doing AND have a FSM for the right year in front of you AND take time document of what goes where. The 2sp system is *much* simplier to deal with, so you might want to return it to a more-or-less stock 2sp system. If should be easy to find the right switch connector housing for the switch; the contacts are easy to remove and move from the old housing to the new housing. First, you must trace each wire from the motor to each pin on your current switch connector and record it; do NOT trust the color codes as they quite possibly no longer match the FSM. It would also be good to record where they go through the bulkhead and their colors on each side for future reference. The FSM shows which contact is where on the 2sp switch housing. All you need do then is move the pin from the old housing to the correct slot in the new housing. Again, I can't stress consulting the FSM enough, but don't assume it matches anything anymore. |

In the 2sp Mopar wipers, the only tricky part is the parking. I have my 1973 Dodge FSM in front of me - I don't know whether you have concealed or non-concealed wipers. I seem to remember, but I could be wrong, that my old 1973 Dart didn't reverse direction when I turned it off - it just completed the cycle and stopped. Both require that the motor be grounded. The 2sp non-concealed wiper motor shows a L (brown) to resistor, P1 (blue), P2(green) and H(red) connection; but I don't seem to have full 1973 Dart schematics. Its wiper switch is not grounded. The 2sp concealed wiper motor diagram doesn't give colors, but requires its wiper switch be grounded. For the 2sp non-concealed, basically, at OFF, power comes from the switch (P1) to the motor (P1), through the park switch, out P2 back to the wiper switch (P2), from switch (A) back to the motor L. When the switch opens the motor stops. In LOW, power goes from the switch (A) to the motor (L). In HIGH, power goes from the switch (H) to the motor (H). For the 2sp concealed, at OFF the switch gives power to P1 and ground to the resistor (to reverse direction); LOW gives power to the resistor and grounds P2; HIGH gives power to H and grounds P2. All the switches I've seen have a tiny letters molded next to the pin. Also, there are varients of the 2sp motor that appear correct, but are different inside. Note that your wiper motor may not be correct; many look identical on the outside, but have different park switches inside. Also, some work the same but park 180degrees opposite, so test things before you put the wiper arms on if you swap motors. |

Hi, sorry to borrow your old topic. I have a question about variable speed motor. My Dart 1967 has the non-concealed variable speed motor, but the wiper switch was 2-speed model for some reason. It worked fine. I found a rheostat-type variable-speed switch which was almost identical to old one. I tried if that worked. The speed adjusting and high speeds work fine, but there's no park. When I turn off the switch, wipers go full speed. Grounds on the switch and the motor are ok. I disassembled and cleaned the switch but there weren't anything wrong there. However the wipers stay at the park position when the switch if turned off and I turn key to acc/run-position. Part #s: Wiper motor: 26380 42 66 2822962 406 2 spd sw: 2820525 23199 2626 1967 V,L,B 2 SPEED WIPER SWITCH,PU variable spd sw: 2770380 020 66 ply, dod, chry, all, 70-71 valian A+E-BODY VARIABLE SPEED WIPER MOTOR SWITCH Thanks for your advice! |

I found out that wipers kept swiping because the motor was turning so fast it skipped over the parking section (the insulator part on the bigger gear face) every revolution. I tightened the armature end play adjusting screw in the motor and now the parking works. Wipers work now, so I guess my parts are compatible despite being from different year models. |
