Volvo Repair: 1992 Volvo 960 Wgn - electrical problem, flash flash flash, 1992 volvo 960

Question
Hi - '92 960 Wgn, 151,00 miles:  Yesterday, the A/C OFF amber-colored button on the instrument panel began to blink and has not stopped.  The following problems occured at the same time:  heater blower fan began working erratically; the power antenna does not work; a blinking amber arrow appears near the tachometer/speedometer and the light that highlights the transmission mode selection of winter/sport/econonmy blinks continuously.  What has happened?  Also, the transmission is slugish when accelerating from a standing stop and has difficulty when downshifting as I stop.  Thanks in advance for a response.  

Answer
it sounds like there are possibly several problems.sounds like a possible bad blower motor or power stage for the fan.

below is how to check codes in tranmissions control unit



in the engine bay on the drivers side near the strut tower there  are 2 small black boxes one has  a wire attached to it.place the wire in the terminal marked 1 on the box marked A .turn ignition key on (not started)press the small button for 1 second and the code will be displayed as a series of flashes.a red led displays the codes.the code will be three digits.small pause in between flashes for a single number long pause between flashes for the next number.example 121 will be flash.....flash..flash.....flash.repeat three times or until first code repeats itself.to erase the code after all codes have been checked hold the button for a good 5 seconds then release the light should light steady,then press for another 5seconds.this will erase the codes.  email me the codes and i will tell you what they are..
