Can someone tell me if this is the correct switch for the rear defrost for a 1973 Javelin AMX? Thanks Darren

'73 Javelins only came with the 'blower type' rear defroster, in which case that is not the right switch. ------------- 74 Hornet Hatchback X twins (since 1977) 62 American Convertible (still worth the $50 I spent in 1973!) AMCRC #513, AMO #384 70 AMX 360 4-speed (since 1981) |

@ramblinrev--you sure about that? I know the heated grid window was available in Javelin/AMX starting in 1970. I've got an original heated grid window from a 72 AMX that I intend to install in my 72 Javelin one of these days. @AMX69Freak--that looks like the switch used in Hornet/Gremlin models. ------------- Jeff Reeves Auburn, GA AMO Technical Editor Currently AMC-less after 30+ years |

'73 and '74 Javelins used a blower motor to defog. -------------  1968 Javelin 360 727 B/W/R 1970 AMX 390 4spd Bayshore Blue 1971 Jav/AMX 401 4spd B6 |

As other's have said, that's the toggle switch for the '71-'72 electrically heated rear window. Starting model year '73 and continuing through '74 had a Ford-Sourced blower motor located in the package tray. The control was a rocker switch to the left of the steering column.
It's humorous to me how AMC went through options. For two years Javelin's had the (IMO, BETTER) electric window while in '73 and '74 you got the blower motor. Does anybody know the real reason why or was the blower motor just cheaper? However in '73 and '74, the Hornet's could still be had with an electric back window yet by '75 it was no longer available in the hatchback.
The Electric Overdrive on Pacers, Hornet and Gremlins also had a strange history of availability/non-availability from (what I've read) as a manufacturer's inability to provide AMC with enough units. ------------- I am genetically incapable of being Politically Correct. |

I have a switch for the 73+ Javelins, the rocker type...The problem is the die cut hole in the lower dash panel for it to mount through...They were cast in the original ones, and I think it would be difficult to do neatly without a large supply of lower dash panels that your going to screw up trying to cut this oddly shaped hole.....Probably the reason they went to the blower was so it could be offered as a kit as well as factory installed.....Bob Reno in Alabama ------------- Thankyou....Bob |

Here's some pics of the switch you're looking for Darren. You could probably make a template of the hole with some tape, mark it and carefully cut it out for the switch. Eddie

Okay, I learned something. Didn't know about the grid window being dropped from the 73/74 option list. I've got BOTH types on hand, so I guess I could use either one. I have a 74 AMX parts car with the blower option plus the complete grid window setup for a 71/72. I do know for a fact that the blower type defogger is straight out of Ford's parts bin. It's the same one used in Mustangs/Cougars/Thunderbirds and other various Fords of the mid 70s. I saved a blower defogger from a T-bird, I think, and it was identical in every way to the Javelin blower unit I already had. However, I think the AMC blower switch was an AMC-unique piece. ------------- Jeff Reeves Auburn, GA AMO Technical Editor Currently AMC-less after 30+ years |

My plan is to take the heated glass out of the 72 I cut up and put it in my 73 Javelin AMX. I didn't realize that the heated glass was not an option on 73/74. I also have a blower so I guess I will just put both in! LOL At least it will be well optioned!!! Thanks for the info guys!!!! ------------- 1969 AMX 390 1973 Javelin 401 1975 Pacer 258 |

I'm sure! And glad we got this figured out. I'm not sure why AMC dropped the rear grid, except there was some "de-contenting" going on in the '73-74 model years. Those were kindof tough times for automakers dealing with pollution control mandates and stronger bumper mandates and seatbelt mandates, plus the Javelin was likely scheduled to be out of production after '74. And then there was this New York mandate for rear window defrosters/defoggers in cars sold there, that went into place in perhaps 1972? The blower type defroster was no doubt the easier way to fill this mandate and keep the price competitive. You could not do the blower type on a Hornet Hatchback or Sportabout or Gremlin, because of no rear shelf. But you could do that on the Javelin. ------------- 74 Hornet Hatchback X twins (since 1977) 62 American Convertible (still worth the $50 I spent in 1973!)

Fluffy: RWD was still available in '75 Hatchbacks, and I believe beyond then (partially since that's the only way you could defog a hatchback rear window!) ------------- 74 Hornet Hatchback X twins (since 1977) 62 American Convertible (still worth the $50 I spent in 1973!)

I find it interesting that the cutout for the blower type defogger is already there in the metal framework under the package tray on the 71-72 Javelins, even though it wasn't a factory installed option.
I did have a NOS blower kit for the Javelin a few years ago. The instructions had a late 1970 date on them, along with a picture of a 71 up style Javelin. I would guess that the blower was a group 15 over the counter option in 71-72.
I think that the literature shows that you had to get a 55 amp alternator if you got the grid style defogger. I seem to recall reading somewhere that you had to get tinted glass too.

Yes, blower-style defrosters were also a dealer-installed accessory. If you got the heated rear window defogger, you got the higher output alternator, and the rear glass was tinted. ------------- 74 Hornet Hatchback X twins (since 1977) 62 American Convertible (still worth the $50 I spent in 1973!)

Are you 100% positive? My 1975 Dealer brochure specifies only that a "Rear Window Defogger" is available on the Hornet (there's no breakdown for sedan, coupe, hatch or wagon). The 1973 Dealer brochure actually has a picture of the *New* "Rear window defogger" and shows a coupe with the blower in the package tray. Oddly, there's no mention of anything available on the hatchback. Only the 1974 Hornet Brochure specifies that an "Electric" window defroster is available on the hatchback.
I know, I'm being nit-picky but most documentation I've seen refers to the blower as a Defogger while the electric grid is a Defroster.
