after we all checked our shoes for dog-poo we came to the conclusion it was the air con. a Google search suggests an aerosol spray fix, if so the q is where do we aim the spray? and any tips or other ideas? cheers, Mike
Mold or bacterial growth in the evaporator is common. Where it is on the V70 I'm not sure, but it'll be down under the dash somewhere. In my 740 I was able to remove the resistor for the blower motor speed control and spray disinfectant in there.
Start Ac place fan on highest speed open hood looking @ firewall on Left hand drive cars spray in the opening in the cowl this is the fresh air intake you did not state what year the V70 is if an early one the pollen filter will be under the cowl replace it if a later one it is under the glove box replace it do not clean the pollen filter just replace HTH Any ? just ask Glenn K Volvo Certified Technician ASE Certified Technician
How long does the fan run for? I've considered building a little timer box to accomplish that on my 740, I've had to spray lysol into the evaporator every few years when it starts to reek like old milk.
The fan waits about 10 minutes after you shut off the car and then it runs for about 5 minutes.
For cars experiencing problems, Volvo has a two stage "cure". They spray an algicide first and if that doesn't solve the problem, they can clean out the affected area and treat it. On our 850 we have had this done a couple times. On the V70XC, the timer on the fan works perfectly.
