Question - Roland you're the greatest it was behind the windshield washer fluid and took about 30 minutes to change.I have one more question for you the transmission works fine when it warm but when it gets below 30 degrees it won't move in drive.If you go thru all the gears it will move in drive and after that it runs fine.Is there anything I can do to fix this?I have 3.3 engine. Thank You once again for your help
-------------------------I took the glove box out and actually had the blower compartment open but didn't remove blower.I looked all over and didn't see it.Will I have to remove the dash to get at it.Thanks again,George

Could you tell me where the fan resistor block is located. I have a 92 New Yorker.I believe that is the problem from what I've read. The fan worked on some speeds and died.So if you could help me out I'd appreciate it. Thanks,George

Hi George,
I believe that the resistor block is located behind the glove box (you probably will have to remove the box to get at it). It is located high up on the panel that separates the passenger compartment from the air intake's external plenum area of the cowl (the trough below the windshield). In this way the resistors are "outside" the car so that they are cooled and can't start a fire, but the electrical plug and the screws that hold the block are "inside" the car. The plug has 5 wires. If you remove the screws the block will be removeable by pulling it rearward.

Hi George,
Correction: I looked more carefully at my '92 wiring diagrams book and found several drawings that show the resistor block to be accessed from outside the car, not from under the dash. Sorry to have mislead you. It is located where I told you, but it appears to be totally accessible from the other side of the panel where I had described it to be. If you look at the base of the windshield you see a trough-like area (cowl) where the air intake, the windshield wiper motor, etc. is located. On the passenger side of that area, behind the windshield washer fluid container and toward the midline of the car you will see mounted on the panel that goes across the rear of that cowling is the resistor block along with its 5 wire connector. The drawing doesn't show the resistors and the plug in any detail but it does show it to be mounted there. It appears to be removeable from outside, but if it is not (i.e. you only see the tips of the mounting screws pokin thru the panel) then you need to go inside the car and locate the unit and its screws from that side. If you can't find it I will send you a copy of the drawing by snail mail (sorry I don't have a document scanner). So let me know if you find it or not and a mailing address if you want the drawings.

Answer
Hi George,
'Glad to learn you found it and it changed out for you. On the transmission, I assume you have 4-speed A-604 type. There is a range of possibilities according to the Chrysler manual. Beginning with the simple and moving toward the more costly:
Engine idle speed too high (above 950 rpm)
Low transmission fluid level
Aerated fluid (because of wrong fluid level)  
Problems with the valve body or oil pump/pressure levels (moderate cost,can be repaired without removing trans)
Internal mechanical problems with clutches, etc. (expensive)

One of the first things to consider is having the fluid drained and the filter changed, but always replace with the Chrysler transmission fluid type 7176 (very important), . Other owners have reported that this often solves minor issues like you describe. But even  before that:
Checking the fluid level: Allow the engine to run for a few minutes before checking the fluid level, and move the shift lever through all the positions before checking the level, with the engine in Park and idling. It should read in the "warm" level area of the dipstick. Smell the fluid to see if it smells burnt, which would also be a good reason to change the fluid.
If changing the fluid doesn't solve the problem then:
A way of inexpensively checking the function of the transmission is to have the Chrysler dealer readout the transmission controller for any fault codes it may have stored (this should cost under $100 to do, and while the codes are not absolutely diagnostic it helps get to the bottom of the problem).
It is good to spend a little money upfront to maintain the tranny because it costs many dollars to do a rebuild. The A-604 is very sophisticated but has higher maintainance issues than a non-electronic style unit. But don't bite for a rebuild until all other possibilites are exhausted. It doesn't sound like you are into that sort of a situation yet (which is commonly experienced by the tranny going into limp-in mode where it will only drive in second gear).
