20cc probs new owner

[DRAPER]

hello,

new owner here so hi all to all, prob not the ebst start for me and my peugeot

brought my lovely pug 206 cc at the weekend, private sale so cant really take it back.

got few problems with it that never really noticed on the terst drive, prob too excited lol

firstly its Pug 206 CC SE 2001 67k

PROBLEMS:
1) sometimes turning on the climate control it makes a whining sound/squealing, but only sometimes, sounds like the fan

2) when changing gears theres a knock/bang which sounds like its coming from the rear to middle of the car, but if i change gear really really slowly theres no knock/bang. only happens going from 1st -4th gear - possibly the exhaust not secured properly? it has an aftermarket sports one on

3) steering seems quite stiff is it normal? last car was MG ZS with silky responsive steering

any help is welcome
