ac on full hot, mixer broken?

the ac in our 98 grand marquis has gone out again!! it only blows full hot. There was a clicking in the dash just before this happened(did the same thing the last time it broke), the last time a AC shop replaced the evap temp mixer(they called it), is this part available aftermarket? how hard to change? the shop charged 200.00 the last time so i believe maybe the lever on the mixer door was broken off and they somehow replaced or repaired it. I know they took out the glove box and worked on the pass side of the car under the dash. Any help would be greatly apprecciated.

Re: ac on full hot, mixer broken?

Have you checked the condenser, which is located in front of the radiator. Is it leaking anything?
