Low refrigerant. An A/C system requires a certain amount of refrigerant to cool properly. If low, it works less efficiently and does not cool well.
Dirty condenser -- The condenser is the heat exchanger mounted in front of the radiator. It cools the high pressure refrigerant vapor after it exits the compressor so it can condense into a liquid. If the condenser is full of leaves, bugs and road debris, air flow through the unit may be blocked to the point where little cooling occurs. Cleaning the condenser should cure the problem.
Inoperative condenser cooling fan. The condenser often has its own separate electric cooling fan. This fan should come on and remain on when the A/C system is operating. If the fan motor, motor relay or wiring is defective, the fan may not be working.
Air or moisture contamination -- For the refrigerant inside the system to do its job properly, it must not be contaminated with air or moisture. Air reduces the cooling efficiency of the system while moisture can freeze and form ice that causes blockages in orifice tubes and metering valves. Air and moisture contamination may be the result of unrepaired leaks in the system, or failing to vacuum purge the system prior to recharging it with refrigerant.
Blockages -- Debris, rust or debris in the system may plug up the orifice tube or metering valve that admits refrigerant into the evaporator. If this vital point becomes obstructed, the flow of refrigerant may be restricted or blocked causing a loss of cooling -- and possible compressor damage as well in systems that rely on oil circulating with the refrigerant for lubrication.
Mechanical problem -- These include things like metering valve failures, compressor wear, a compressor clutch that fails to engage, bad pressure switches, etc.

The 2006 Volvo is electronically limited to 250 km/h. It also goes from 100km/h in 6 seconds!--------------------------------------------------------------------------------- FGTech Galletto 2-Master EOBD2
There are 2 types of bulbs that i see,here's a link to look at,Application: Low beam Without halogen capsule headlamps.Application: Low beam With halogen capsule headlamps.Sure you have the right one in.
It is likly a dirty relay. This is located on the passenger side by the ratiator fan, with a black plastic cover over the box. Be sure to disconnect the negetive side of the battery before working on any thing electric. Clean the relay contact points using 200 grid sand paper (wet-dry black paper), You can use a spray electric contact cleaner as well, which you can get at most autoparts stores.
Have same issue with my xc70 cold to coolish on drivers side and warm to hot on pass... slowly, with driving, pass side becomes cool. Slight swoosh sound from dash attributed to A/C is intermittent. Thought to be kinked tube or puncture? : (
Possible problem with the alternator not putting out enough voltage. I had the same problem with my 2002 XC70, putting in a new alternator fixed it. I used a local mechanic who I found on the car talk web-site. Low Cost Volvo parts can be purchased at FCP Groton.
You need to remove the front bumper. Five push clips along the hood line, remove the headlight wipers (if equipped), one T25 screw in the front of each fender well, then two 12mm bolts under the headlights (1 each side). Then there are 4 10mm bolts holding the headlight in.
