SOURCE: 1991 Chrysler Imperial Problem

Your car has the A 604 transmission also called the 41TE,and it uses an input and output speed sensor mounted on the transmission.These speed sensors feed information to the Transmission Control Module (TCM) one of the vehicle's computers, which calculates vehicle speed,and sends a speed signal to the speedometer in the dash.It is a totally electric speedometer and odometer,no cable drive like old cars.So the first step would be to scan the vehicle's computers for diagnostic trouble codes,as a malfunctioning speed sensor can cause your symptoms,sometimes accompanied by no upshifting,or erratic shifting.All the components involved in the system have to be deemed good,or repaired if a component is found defective.With the scan tool,there is also a data stream available for viewing the systems while the engine is running and the car driving,to look for malfunctions.Within the data stream,i can look at the speed sensors individual outputs,and see what the computer is seeing as far as inputs and outputs.If the speed sensors check out ok,and are functioning properly,then the problem would likely be the instrument cluster,including the speedometer in the dash.But other components have to be verified good before drawing conclusions.

It is the speedometer that doesn't work? What problem do you have? Does the transmission shift or is it stuck in 2nd?

SOURCE: The AC and power windows just stopped functioning

Take a look at thse two and replace them:

Fig. 3: Relay and flasher module — Dynasty, New Yorker (1989–93), Fifth Ave. and Imperial

(This is for the power windows)

The fuse panel, which contains fuses and circuit breakers, is located behind the glove box door. Additional fuses are in the Power Distribution Center located near the left side strut tower in the engine compartment. Each item is identified on the cover of the Power Distribution Center.

There is an additional relay module (relay and flasher module) located to the right lower corner of the instrument panel (Dynasty, Imperial and Fifth Ave.) or behind the cup holder (New Yorker). A relay or flasher can be removed by pulling it straight down from the module.

Speedometer not workin on a 1990 chrysler imperial, is it a cable disconnection or is there a module? the mechanic that looked at it said he doesn't think it has a cable.


If you have the digital dash the mechanic is probably correct. The "body control module" is located under the passenger kick plate and controls a multitude of unrelated functions like odometer, fuel gauge, and headlight covers. Replacement must be the same part number, and critical factors are digital dash, and EVIC (overhead display). I just replaced mine last week from the local pull it yourself yard. Applicable donors are '89 & '90 Imperal, Dynasty and New Yorker.

Replace speedometer cluster on my '95 Honda Accord DX


I would have the trans speed sensor checked before removing dash assembly. The speed sensor is an analog sensor that sends a signal to the dash. It is located near the trans output shaft attached to housing with a small bolt. It is gear driven and quite easy to get at. It is also subject to heat and road conditions, makeing this the prime culprit in speedo problems. Hope this helped. Moe

you said the speedometer is fried ...i take it that it dont work at all. this may be caused by a bad vehicle speed sensor or input or output speed sensor. this can also cause the tansmission to go into what is called a limp in mode. you need to have the codes read from the transmission controller
