This is how the turn signals are wired on my car:



                    ---------
    +ve:------------|FLASHER|-----------
                    ---------          |
                        |              |
                        |              |
                        |              |
                        |              |
                  ------------         |
                  |DASH LIGHT|         |
                  ------------         |
                        |              |
                        |         ----------
                       -ve        <<<STALK>>>
                                  |         |
                                  |         |
                                  |         |
                          ------------   -------------
                          |LEFT LAMPS|   |RIGHT LAMPS|
                          ------------   -------------
                                  |         |
                                  |         |
                                  |         |
                                 -ve       -ve

Note: - both circuits use the SAME flasher unit
      - the wiring for both circuits is shared upto
        the turn signal stalk

The reasons you may one side blinking slower than the other are :

- One (or more) bulbs not working
- Bad earths on any one of the four lamps (or 6 if 2 reapeters are used)
  (Do you have 1 or 2 dash repeater lights ? - check each of them) 
- One (or more) bulbs is of different resistance (remember there are 
  a total of 6 bulbs in the circuit)
- Are any of the bulbs brighter than the rest ? (In the UK, turn signal
  lamps are a different wattage to those in the USA - I think the UK is
  25 Watts and the USA is 21 - can anyone verify this ?)


Try :
- Moving bulbs from one side to the other and see if the slow blinking
  "follows" the bulb
- Thoroughly clean ALL connections, including all "bullet" connections
- Thoroughly clean the earths and verify that each lamp is using the
  correct earth and not going though another circuit's earth.
- Isolate the circuit from the car and use separate earth's straight 
  to the -ve terminal of the battery

I bet you you have an earthing problem, or a corroded connection.

Best of luck
