[s-cars] Heater? Leak

[Bill Mahoney]

Folks,

My 92' S4 sister based in CT, reports coolant on here right foot.  She
said its slippery and if so it sounds like coolant.

Local supposedly trustworthy repair shop thinks it's the heater coil.  

Has anyone BTDT?  In my few years of list watching I can not recall any
reported heater failures.

Any ideas how extensive a repair this might be in cost and labor?

BTW she loves the car for sure but can not manage the repairs and may
buy a neu S4 springtime or sooner.

So, there may be a 92 (no suspension mods necessary) black with grey
available soon.

As usual TIA.
