Haven't used the deck for a while. Went to use it, both sides do the same thing. Everything seem to engage but the tape will not move and the systems attempts to auto reverse every few seconds. Any ideas?

Re: Dual tape deck inoperable
Clean the rubber pinch rollers with an alcohol swab. the tape is not getting required "grab" on these rollers and not pulling tape. the auto reverse is an attempt to rewind the tape because of confusion with no tape movement.

if one reuses the tape often, ive found that the tape stretches and no longer covers the entire record path (or play path) , i still have a few cassette and reel to reel decks that I still use , and since the tapes are hard to find now I keep reusing the tapes more and more 4 the same thing , I guess its been like in the past year ive seen this tape stretching thing happen now
There are 2 long switches, maybe 4" long, called record/play switches. These can certainly cause this. Try cleaning them with the power unplugged. You would turn the cassette deck on end, so the switches are vertical. Use LPS-1 or LPS-2, and spray a very small amount in the end. Work the switch back and forth and see if that helps. Good luck.
Loose belts and lack of lubrication. Dual cassette decks are built to minimum standards so that it does not take much to push them over the edge to be non-functional. It is almost like they should provide a tape deck repair course with these types of units as it is most certain that you are going to need it. They want you to throw it away and buy another one. This is where the throw away economy started.
Yes, the belts need to be check and idlers or whatever drive mechanism that is used in that system. Dual deck units are among the most unreliable units there are and a reason I tell people for the last 30 years not to buy those things. Almost most of the time they are not worth fixing due to their poor performance at the end. These are facts not just opinion.
The solution to the problem comes from recognizing the type of transport the unit uses. This can be discovered by looking at the working side or by a person who has some experience working on these. Chances are there is a stuck flywheel assist mechanism and just because the belts are no broken or not turned to goo, that does not mean they are good. Also does the capstan motor turn? If it does not, there is no way the mechanism can right itself and that might mean a new capstan motor. Dual cassette decks were built for profit not for a long lasting unit- that is why the thrift shops should be full of them and why most of them will not work.
I have not seen those to a large extent due to their value not being worth a repair. I did work on them at Teac though. The capstan motor of the right side deck sound like it is burned out. I have some motors here so it is just a matter of if you want me to work on it or not. I get a lot of units in all the time- I am Skywave Tape Deck Repair in Chicago area.
I have the same unit which had the same problem. It has to do with dirty contacts on each tape mechanism.
Remove the main cover and look down on each tape mechanism. You will see 4 contacts on each unit. These come in contact with the tape. Remove each unit by removing 4 holding screws.
You will now be able to spray some contact cleaner into the front of the plastic contact cover. I removed the covers on both of the second from the right contacts so that I could clean them with an abrasive. These are the main ones.
Put everything back the way it was and the tape deck should work great.
If this is a deck where the tape slides in horizontally, like most car stereo tape players, you may have a broken or slipping belt. The fact that you "haven't used it in a long time" suggests a worn-out belt.
In my car stereo, the belt slips when it's cold and won't play or eject the tape. After a few minutes, the unit "warms up" and the belt starts turning. Then everything is fine.
