Some background: 2007 Honda Fit Sport with AT The sypmtom: A/C works great, it just seems to take 10 minutes into a drive; sometimes changing speeds/vent setting/to defrost can encourage it to kick on sooner, but once it turns on there isn't a problem and it works fine. If I restart the vehicle without it sitting for hours it tends to not take that time to kick back on but may or may not work again right away. Why would it do this? I was in a wreck last fall. Hit a deer and fixed it cheaper using a family friend for the labor; as the radiator support was bent slightly at the top (deer flipped into the hood and pulled the hood latch toward the engine several inches bending the radiator support), but the car drives fine and I was being quoted by pro shops to replace the radiator support (I understand they wouldn't want to warranty the work without ensuring it wouldn't be a problem later but we're talking an additional $1,500 b/c of Honda price on that piece to weld in). I digress, before the wreck the only symptom with A/C trouble was corrosion inside the passenger compartment fuse box causing the blower motor to not work or be intermittent/weaker. This came back and removing/replacing the fuse (which is still fine if not for slight discoloration on the prongs) fixed the blower motor issue itself. The delay in the A/C compressor actually engaging and working during drives happened this year though so it wasn't immediately following the collision and I'm not sure what to think. My first thought was I wondered if a freon leak created a low charge to the system. Is this what a low charge does? Seems electrical in nature to me; as if a relay or switch isn't engaging properly when first starting. Once it turns on, the compressor seems to work just fine. Any thoughts? Can't afford to go to a shop yet and the summer heat makes some drives after work brutal to start. Thanks! PS: Apparently, the rear hatch has a slight leak I haven't traced down, yet. So, there is at times ingress of water when it rains which collects into the spare tire area. I live in Atlanta. It's humid on top of this. EDIT: Could it be a problem with the expansion valve?
