HELP!! 1998 avalon ac, no heater, blower, prob autoclimate

Saw this in another post. Symptoms: =A/C int. INOP
=The Ambient Temperature display goes blank or displays "-"
=Fresh/Recirc indicator light INOP
=Mode Indicator Light Inop
=Blower Indicator Light Inop
The Fix for this involves replacing
A/C Amplifier (ECU) Part #88650-41030
Air Inlet Servo Motor Part #87106-07050
Servo Link Part #87151-07010

Nothing works no blower for heater, defroster, ac. no indicator lights, etc. I replaced the ac amp form ebay no change. Trying to get to servomotor by removing blower housing but can't get it out. Followed service manual instructions, all fasteners, but housing seems attached at left side. Right side of housing has the ecm, cruise module, harnesses, packed. What should I do next? I am no notice but at wits end with this one. Is there an easier fix or way to check servo? I unplugged it at blower housing and no change. An earlier post years ago said a garage fixed it without replacing parts. Really need someone knowledge on how to do this. Thank you in advance. :crying:
