Disco 1 97 disco air-conditioning problem

Hi from Australia queensland,I have just replaced my aircon gass and replaced the drier with a new one. I am trying to find a fault with the power not getting to the cooling fan, right front. The left one works .Could it be the yellow things on the passenger side thats gone bung.The 2 switches on the dash light up so they have power.Its starting to warm up here at xmas ,thanks to all replies.

As the fans are wired in parallel and u have one fan working suggest that the other one has seized or has an electrical fault and requires a repair or replacement.

Thanks for that discool.Will check that out.
