1997 V70. The climate control has just recently decided that the lights needs flash for a bit each time the key is turned on, hadn't paid much attention as it all seemed to work, but with a couple of cold nights I have just noticed that the temp on the right side (drivers side) doesn't seem to make any difference to the temp coming out of the vents, however changing the left side seems to adjust temp out of left vents fine.
What are the likely solutions, options, implications.
319 000km it is good nick, wondering if it is likely to be an expensive repair. What is the life of a car like this, don't want to over capitalize on it if it is a waste of money. Is the fix a DIY.
Thanks Jeff
