1989 Telstar hazard flasher location

[Zaphod1000]

Hoping someone can assist. I have a 1989 Telstar TX5 Ghia that we have decided to sell. Went for a pink slip, only to find that the hazard flashers don't work (bugger). Never used the damned things. Anyway, the fuse is fine, but I have no idea where the flasher unit is. The hazard flasher switch disables the indicators, so, I assume the switch is OK. Next up in the flasher unit. So, if anyone can tell me where the find the damned thing is, I can fix/replace it and sell the old girl.

Anyone want to buy a pristine 1989 Telstar Ghia (5 speed manual box, one lady owner, 160,000 clicks)? Any ideas on value?

TIA
